Are there, in fact, any such implementations? Which profiles beyond
S and F are used with image/tiff? There were no implementations
that used "image/tiff" with any profiles other than S and F listed
in any of the interoperability reports so far. In searching the
Internet for descriptions of Internet Fax implementations, I can't
find any that use "image/tiff" for profiles other than S and F.

If the consensus is that this statement is true, then could someone
who believes this statement name any of these "existing
implementations",
please?
