As the learned Judge in Gilbert and Sullivan's Trial by Jury pointed out, "A nice dilemma we have here that calls for all our wit ..."
It appears that Adobe, as official keeper of the TIFF spec, has finally adopted Zip/Flate compression as part of the "official" standard. However, they have assigned it Compression Type 8, and have recommended obsoleting Compression Type 32946 (0x80B2).
Oh, and that has BEEN documented for about 2 years now (although the note about the obsolete type is new).
