Metroid Prime 1 for the GC doesn't require any special settings for the scan visor, and Super Mario Sunshine only has the goop collision detection break if you enable Store EFB Copies to Texture Only – enabling Skip EFB Access from CPU just makes Mario turn as if he's constantly behind an object or something along the lines of that. But yes, there are problems with forcing Skip EFB Access from CPU to be enabled, especially the one you mentioned in Super Mario Galaxy.
