Hiya! :-)

Yes we're fine making this change to the spec and the implementation
in the upstream Mali driver. As you say, we don't expose this on Android
as it has its own EGL_ANDROID_image_native_buffer which achieves much
the same thing. So it is really only X11 & fbdev.

I think Dave G (ARM) will raise a Khronos bug on the spec and propose
some new language. This will give other vendors a chance to comment,
though as you say, I believe ARM & Mesa are the only implementations
so doubt there will be any objections.
