Should this be clarified with Mesa folks upfront? If you believe that

is built.

Agreed ... I'd rather not drop the check until we hear from upstream the reasoning behind it.

This patch is really about the first line:

Even if we had an opengles distro feature that solved the GLES vs OpenGL issues, having a 'ANY_OF_DISTRO_FEATURES_class-target = "opengl vulkan opengles"' line instead still wouldn't make sense (although it would solve my problem), because mesa doesn't require any of those features. This line is effectively saying it depends on the things it provides.

I will raise the build issue with mesa, but I think it's not related to the core issue here. There are no responses yet, but I see https://gitlab.freedesktop.org/mesa/mesa/-/issues/4176 was raised a couple of weeks ago with a very similar issue.
