Not unless you convince me otherwise. I don't think I'll be able to
verify that said tests work however.

Where is this template?

GL_ARB_texture_view doesn't interact with EGL images at all from what I can see.

It should just return EGL_BAD_VIEW_MESA then.

If Mesa does const by default, then sure.

Because it's not implemented. I prefer not to touch code I won't even
manually test after (no pixmaps in Wayland).

I could probably add something.

Surrounding code had it.
