It's also a less of a problem in the current version of wine because we do not require OpenGL 4.3 for SM5 anymore. However, I think it still disables a better codepath for SM4+ interpolation qualifiers.
I don't think it should, but didn't check. When requesting a core profile, the driver is allowed to return a higher version profile as long as it's compatible with the one requested. Of course if there's e.g. GL 4.4 core functionality we'd like to use it would probably be better to list that explicitly in supported_gl_versions[] instead of relying on the driver to give us the highest compatible context.
