Thank you@jdm,
Do you think it would make sense? Any opinions on this?

The most likely possibility is that webrender is rewritten on top of wgpu. That's still an enormous project with no timeline. Once that exists, the GL parts of Servo would need to be rewritten on top of wgpu/some platform-specific renderer as well (surfman, compositor, webxr, webgl, media). I don't see that work happening unless it's funded by a company that has a use case which cannot rely on opengl, and they have engineers to throw at the problem.

I guess one other possibility is if there was an opengl implementation that was backed by vulkan under the hood, which could theoretically trade off some performance to avoid having to rewrite everything. I don't know enough about the graphics landscape to say if this is realistic or not.

Thanks, that's very informative. There'szink, asopengl implementation that was backed by vulkan under the hood.
