Every analytics tool that provides webmasters with statistics about
what sites send them the most traffic, what search terms people use
when reaching their site, etc. would immediately break.  This would
make webmasters very unhappy.

On the other hand, Trac would stop uselessly, annoyingly, and
non-removably highlighting all the places in the page where search
terms appear, when you come from a search engine.  This would make me
happy, so I guess it's a wash.  ;)

Seriously, removing Referer (or making it origin-only) probably isn't
going to actually break very many sites, since it's already not very
reliable.  But it would sure upset a lot of webmasters, because it
provides a lot of useful info.
