Of course, but OpenPGP is sensitive to the strengths of all of its
hash algorithms (as noted in the "Security Considerations" section).
If TIGER was put into the standard with less care because it couldn't
be used anyway without an OID, then now is an appropriate time to
decide whether it should be in the standard or not.  Mind you, I don't
know the history here - there could have been significant care taken.

I'm not for or against using TIGER in OpenPGP, but my feeling is that
if we are going to include TIGER, then we should do it intentionally,
with all due care taken.
