If you list versions, you have to list explicitly all later versions (i.e. es3,
gl3, gl4 etc.)

I think you don't need to restrict it though. We should be able to assume that
the driver will only expose the extension on a version of the driver that
supports it (either way, we fail early if we don't have es2/gl2).
Just leaving out the gl_versions line should work ok.
