Should we eliminate IP address lookup for incoming e-mail?

I run an IDENT server on my tiny system; I have nothing to hide.

The FSF runs an IDENT server on their systems; however, it always
reports the user name we-refuse-to-spy-on-our-users.

I look at Received headers from time to time when fighting spam, and
in my experience a surprising number of e-mail servers do run IDENT
servers.  Of course, the information is pretty much always useless.
