Of course its not backwards compatible. Like I said composite is
EXPERIMENTAL.. so users of it should expect things to not work
perfectly. Users *have to turn this on*, so it is not going to break
anyones desktop out of nowhere. Mozilla/Macromedia/Whoever should take
this time period to fix there apps to work with future versions of X
with the composite extension.

I don't. But they need to adapt to these changes. We shouldn't work
around there problems. 

I would even go as far as to say that any app that doesn't get fixed
during the experimental phase of the composite extension should probably
be abandoned by it's users -- it is obviously unmaintained.
