ProPhotoRGB is actually a renamed version of ROMM RGB. So it makes me wonder if that should be used as the base, with ProPhoto RGB as the alias, if aliasing can be supported.

Likewise sRGB is derived from ITU-R BT.709 (or Rec. 709).

Likewise "adobe rgb" does not exist, it's specifically "Adobe RGB (1998)" and for that matter I'd quibble with wikipedia for calling it "Adobe RGB color space" which is not strictly correct either.
