I just did a quick once-over on the PR and am pretty shocked by how "simple" it is. For switching the background graphics library, I would have expected this to be some pretty delicate surgery. But the "meat" is swapping out the old abstraction layer for the new one (500–600LOC) then `s/blade/wgpu/g`. There's a little more to it than that, but not much.

I'm already a Zed user, but to me that's an extremely good indicator of the engineering quality of the project.
