As far as I used appdb, all entries I browsed seemed to be for vanilla wine (as it should be).
Don't forget that one of the killer features of vanilla wine: its SDK it only 2 small C compilers, an ELF one, and a COFF one. Namely, tinycc (ELF/COFF) should be sufficient.
I don't see a small C compiler as a feature of any importance really in this case. Especially if gaming is concerned. All relevant use cases support all needed compilers.
It wouldn't be a platinum rating, but gold and silver rating allow library overrides.
