It is not just fast-import. Git's author field looks like an rfc822
address, but it's much simpler. It fundamentally does not allow angle
brackets in the "name" field, regardless of any quoting. As you noted in
your followup, we strip them out if you provide them via

I doubt this will change anytime soon due to the compatibility fallout.
So it is up to generators of fast-import streams to decide how to encode
what they get from another system (you could come up with an encoding
scheme that represents angle brackets).

I'd think that if a remote system has names with angle brackets and
email-looking things inside them, we would do better to stick them in
the email field rather than putting in a useless <none@none>. The latter
should only be used for systems that lack the information.

But that is a quality-of-implementation issue for the import scripts
(and they may even want to have options, just like git-cvsimport allows
mapping cvs usernames into full identities).
