Likewise, most developers could care less about accessibility --- probably
the same developers who don't care about IMEs --- and they just won't bother
using your proposed APIs.

"Don't use canvas for text editing" is a better, simpler, stronger message
than "here's a bunch of APIs you should use to get text editing half-working
in canvas". Let's try pushing that message and see what happens! There's not
a proliferation of canvas-based text editors today.

(FWIW lack of support for IMEs disenfranchises an order of magnitude more
users than lack of support for accessibility.)

Apple, Microsoft, Google, Mozilla, are you going to implement the

As a Mozilla developer, I would not make caret and selection tracking for
canvas a priority until it's clear that discouraging authors from
implementing text editing in canvas has failed.

they received the message with great eagerness and examined the Scriptures
every day to see if what Paul said was true." [Acts 17:11]
