Patrick, What I am saying is also noted in H71 for instance:
"Authors sometimes avoid using the fieldset element because of the
default display in the browser, which draws a border around the
grouped controls. This visual grouping is also useful and authors
should seriously consider retaining it (or some form of visual
grouping)".
Likewise, H63 notes, "header cells marked up with td instead of th.
Sometimes, authors use this to avoid the display characteristics
associated with th and also do not choose
to use CSS to control the display for th".

I did not say it is easy to come up with a normative SC.
All I am highlighting is that some of HTML's default styling for
elements does aid accessibility and need to be identified / documented
as such so developers will think twice before replacing them.
I gave the example of handwriting feature on a mobile device  as an
example of an OS feature that  gets disabled; the S508 para I quoted
refers to OS features. As this is not a matter of presentation that's
why I noted  the reasoning separately.
Best regards,
