GHC includes them by default, and they cannot be turned off. This is a
bug (but we're unlikely to fix it).
My only comment is that some of the extensions you've formalised are
probably a bit too experimental or GHC-specific to be included in the
general Extension type. I'd leave out InlinePhase for one.
PatternTypeAnnotations should probably be called ScopedTypeVariables.
I'm not sure what UnsafeOverlappingInstances does compared with
AllowOverlappingInstances and the other instance-related flags.
