Note the operative word "should" ... "as necessary".

That specification came from a world where most mail was stored
in a single file per mailbox. In the one file per mail Maildir, that
need to lock does not apply. 

Note that IMAP has gone away from that requirement too (of locking
a mailbox exclusively).

Personally, my experience has been that for large POP sites - especially
ISPs - using traditional locking pop servers, tech-support spend a certain
amount of their life removing locks from dropped user connections. Switching
to unlocked POP servers gave them free time.

I think the archives will show that this has been discussed before. And some
prefer to interpret "should" as "MUST" in RFC parlance. In other words not
everyone agrees with the interpretation of the RFC as I've just described.
