> Skia automatically will draw a texture-backed-bitmap to a gl context, and a ram-backed-bitmap to a gl context. It does not automatically do the reverse: texture-backed-bitmap to a ram-backed canvas.

Why not?  Seems like if I have a texture backed bitmap and I tell skia that I want it rendered into a ram-backed canvas that a readback is required.  What's other behaviors could be valid?

That's another argument for why this should be handled by Skia and not in WebKit code.
