Section 508 mapping of WCAG 2 to FPC

Hey list, a bit of a WCAG-adjacent question, but: while reviewing 
https://www.section508.gov/content/mapping-wcag-to-fpc/ for some 
internal documentation, I came across a few entries that seemed odd - 
I'm hoping that folks (thinking of Bruce Bailey / USAB here for 
instance) can elaborate/provide some further context.

* 1.1.1 Non-text content: am I right in thinking that it's marked under 
"Without Hearing" and "Limited Hearing" when the content in question is 
audio (e.g. a sound cue that has no text alternative/equivalent)

* 1.2.1 Audio-only and Video-only (Prerecorded): I'm assuming that for 
something that is "audio-only", that's when it falls under "Without 
Hearing" and "Limited Hearing", and when it's "video-only" it falls 
under "Without Vision" and "Limited Vision"

* 1.3.3 Sensory characteristics: shouldn't this also fall under "Without 
Perception of Color" if the sensory characteristic being used/references 
is color?

* 1.4.1 Use of colour: I assume this doesn't fall under "Without Vision" 
if the information conveyed through just colour is also conveyed 
programmatically (so that it's announced by a screen reader, for instance)

* 3.1.1 Language of page: why is this marked under "Without Hearing" and 
"Limited Hearing"? How are these groups affected?

* 3.1.2 Language of parts: why is this marked under "Without Hearing" 
and "Limited Hearing"? How are these groups affected?

* 3.2.4 Consistent Identification: it's unclear to me why this has also 
been marked under "Limited Manipulation"

* 3.3.1 Error identification: am I correct in assuming that "Without 
Perception of Colour" only applies if the reason why something fails 
this SC is because they're using colour alone to indicate an error? 
Otherwise, if errors are not indicated in general, would this not be 
something that fails for *all* groups?

* 3.3.2 Labels of instructions: while I understand why this would affect 
people with "Limited Language, Cognitive, and Learning Abilities", it's 
unclear why "Limited Vision" has also been singled out as a group 
affected by this.

* 3.3.3 Error suggestion: am I right in thinking that this has been 
marked under "Limited Manipulation" under the scenario where a site/app 
should offer an easy way for a user to select (e.g. from a list, or 
radio buttons) the correct value they intended to use - rather than in 
cases where the solution would be to provide error suggestion in text 
(leaving the user to still enter it/correct their entry manually)?

* 3.3.4 Error prevention (legal, financial, data): wondering why this 
has been marked as affecting almost all groups, *but* with the notable 
omission of "Without Speech" and "Limited Reach and Strength". Is this 
just because there's an overall decision that *none* of the WCAG SCs 
relate to those two categories? If the intention is that a lack of error 
prevention affects everybody and is important enough to flag, then I 
would have thought this would affect *all* groups. Otherwise, I'd be 
interested to know if there's specific rationales for the groups that 
*were* marked as being affected by a failure of this criterion (and if 
there's any particular nuance of failure that would only relate to 
specific groups - e.g. I can't currently think of a scenario where a 
lack of error prevention may be problematic for a user "Without Hearing" 
and "Without Vision" but fine for a user with "Limited Reach and Strength")

* 4.1.1 Parsing: am I right in thinking that this has been flagged under 
"Limited Manipulation" only for cases where incorrect/broken markup also 
results in problems relating to, say, keyboard operation/focus order? 
Further, I'd be interested to know what kinds of failures of this SC 
would affect people with "Limited Language, Cognitive, and Learning 
Abilities".

* 4.1.2 Name, role, value: similarly, I'm wondering why this SC is also 
flagged under "Limited Manipulation" and "Limited Language, Cognitive, 
and Learning Abilities". Is the assumption that users from these 
categories also often use assistive technology, which will be affected 
by this?

Apologies for the flood of questions, but I'm hoping to bring a bit more 
clarity here...
