It was *very* important when people were cut& pasting pgp-signed emails 
around (and the contracts I eluded to earlier) but this all disappeared 
when more sophisticated techniques turned up which included MIME and 
also PGP encryption itself.

The last time I had a canonicalisation nightmare was in about 1997, 
sitting in a tent hand-crufting bits of a PGP book back together.  With 
a bunch of Americans giggling in the background to accentuate our pain.

That amusing memory aside, I think yes, canonicalisation has kind of 
shifted down in priorities and would be a contender for occam's razor.
