Hey all,
I am skeptical about a point system as part of a conformance model for
accessibility. I think a point system is a cool idea, but not as part of
the conformance model.

Point systems are great if you have different things you could do, that
lead to roughly the same end result. For example, the airports with bike
racks example is something that keeps coming up. You can do any number of
things to get more people to leave their car at home. Better public
transportation, encourage biking, encourage carpooling, etc. Any one of
them reduces cars, and all of them do it by a lot.

Accessibility doesn't really work like that. Keyboard accessibility and
visible focus aren't interchangeable. Users need both of them. The few
places in WCAG where more than one option is acceptable, we've already left
the solution open (example: Bypass Blocks) or we've specified the available
options (example: Audio Description or Media Alternative).

I can't see us ever agreeing that, if you do more for people with learning
disabilities, you don't need to do as much for people with low vision. Any
point system we use can't be at a conformance layer or guidelines layer. It
has to be narrow, so we don't make the needs of one group interchangeable
with another. That means point systems at the success criteria layer. WCAG
already allows for this. Think of how color contrast is done. Two success
criteria, one at AA, one at AAA, using the same measurement tool, with a
lower threshold for AA and a higher one for AAA.

I can certainly see us having more "point systems" for different
requirements. You could require 8 points for non-text content at level A,
and 12 points at AA or whatever (just making up numbers). It might also be
possible to create a point system that will work for lots of success
criteria. But I don't see that working at the conformance level. A point
system where you exchange one user need for another seems pretty
problematic to me.
