No, I certainly do not intend to advertise 3.0 because we cannot implement
things like branching, dsx/dsy or vertex textures, but I'll propably
advertise 2.0 some day, if I feel like causing a lot of extensions(Or I think
that our shader tests are good enough to safely do this).
The ARB shader backend tries to eat everything it is fed with though, even 3.0
shaders. Some games require a specific shader model, but use only a subset of
it that is supportable. Having the code to support some 3.0 specials makes my
life easier since I can just go and lie about the caps on macos for specific
games(e.g. in crossover). I don't put special focus on SM 3.0 support, but if
I come across something that is easy to add, I'm adding it. Also, some day we
may implement the 3.0 features using the NV extensions.
Of course if it's preferred to keep the arb shader backend clean from version
== 3.0 checks I can keep the things I have in my junk branch, as long as I
don't have to explain why I'm not submitting $GAMEFIX to Wine. Pretending SM
3.0 support is a hack, implementing the parts of 3.0 we can implement
properly isn't IMHO.
