The opengl-glew egg uses it to conditionally build with GLES support.
There should be more eggs, but it's tricky to tell which.

I've expected to eventually run into this and even planned on eventually
using the feature.  Then I found that it's mostly useless to me as I
only use Linux these days and haven't run into a different usecase for
