> First of all, good old backwards compatibility. There's large codebases still written in Flash, or perhaps things that are in Flash that will never get updated ever again (browser games being a big one), and people would like them to work even after Adobe's dropped out.

It's a fair point that wanting to retain the ability to run this content after there is no (working) Adobe plugin is desirable, but is the browser the best place for this? We don't demand that each version of an operating system is able to run all old application software for that OS; the preferred way of being able to do this is through virtualisation, and I'd argue that's probably a better way to do this, too.
