We also use Skia's GL backend on some platforms, and D2D on windows.

If Flash uses a 2d-like API like skia/cairo/etc., then it is probably not worth the effort to reimplement the awful-for-GL parts of those APIs. If there's some performant subset that can be identified, then yes, doing a WebGL path for that would have a higher performance ceiling.
