No one is suggesting to change how CSSOM or display:none works. Please
see my change proposal, it does none of these things.
It sounds to me like you are worried about various changes to the
internals of browsers. So far none of the actual browser implementors
have expressed this concern. In fact, both Maciej and I have said that
this seems implementable and that we have to write similar code anyway
to support <canvas> accessibility.
I'd have a lot more understanding for you being concerned if you
actually were implementing a browser. I much rather that we ask people
who actually implement browsers what is implementable.

This seems like an argument against adding any features to HTML5 or
any other standard to improve accessibility. Since any time you do
that you risk increasing the digital divide since only newer browsers
would support said standard.
You are of course entitled to your opinion. But I strongly disagree
with it. Especially in the context of writing new webstandards which
is what this mailing list is about.
