I might even suggest going one step further and make that an _EGL_WARNING,
so that users are always informed of this by default, without having to
set EGL_LOG_LEVEL.
I think most users don't want to disable their hardware, so the annoyance
if this warning showing up for users who want it should be completely
offset by the usefulness of this information for those who don't.
