*NNTP* says that you can't send malformed junk, and verifying that what
you received is not malformed junk requires scanning the entire headers.
It's interesting (and rather eye-opening) to hear that UUCP-only sites
apparently don't have to check the syntax of messages, but it's not
particularly relevant to the real world.

I really don't see any useful purpose served by optimizing the article for
faster processing by lazy UUCP-only sites.
