Proliferation of SCs

My previous email from my other address bounced so apologies if this is a
duplicate...

There are currently 38 A and AA SCs in WCAG 2. I think reasonably speaking,
the WCAG group can't entertain a 2.1 with more than 12 or so new SCs at
level A and AA, maybe up to 16 if we REALLY push it. That is from ALL TFs.

Yesterday we presented quite successfully to the WCAG group. We presented
14 SC, some of which are still just internal proposals to the Mobile TF
rather than consensus SCs...  there is concern among some members about the
number of new SCs we are putting forward when combined with other TF SC
proposals.

I would like to make a suggestion that we pair down the number of SCs we
propose. Specifically, the SCs requiring Pointer functionality. Patrick
made the important comment that their inclusion is more for "completeness"
than to overcome and real barriers that users with disabilities currently
encounter on the web. We really only have theoretical barriers for those
SCs right now.

Although I appreciate that rational of wanting to have a consistency
between keyboard and pointer requirements in WCAG, and also appreciate that
the first choice would have been an integration of Pointer and Keyboard SCs
using a ore abstract SC at 2.1.1 and 2.1.2, so there wasn't a proliferation
of SCs, I think the confusion about the number of SCs we are proposing has
caused some in the WCAG  group and staff to go back to considering a
separate extension for mobile which I feel would be a major step backwards.

My proposal is that we finalize our new SC proposals at these:
M2: Target Size
M5: Touch with Assistive Technology
M7: No Focus Trap
M8: (No) accidental activation
M9: Pointer inputs with additional sensors (was: Advanced pointer input)
M10: Device sensors (was: Device inputs)
M11: Speech Input
M12: Single key shortcut alternative
M13: Orientation
M14: Non-interference of AT

And explore further
M6: Input-agnostic (was: Additional inputs reliant on assistive
technologies)


I'm proposing we drop for
​WCAG Version ​
2.1 the following:

M1: Pointer
M3: Pointer gestures
M4: Keyboard with AT (that remaps key input)

This will allow us to focus and develop the other
​ SCs in our short time remaining.​

Cheers,
