Makes sense. However, if the currently implemented subset is sufficient for at least /some/ applications (i.e. Office 2013, which is kind of an important application), would it not make sense to make this a setting somewhere? Not talking about winecfg, but how about a regkey HKCU\Software\Wine\Direct3D\ShaderModelVersionOverride?
Actually there is one already, you can force enable core profile support by setting the MaxVersionGL key to the (DWORD hexadecimal) value 30002.
This is still work in progress so don't be surprised to see stuff crash and burn in various ways for the time being.
