I do this; however, I use qmail's extension addressing scheme to put each
mailing list in a different Maildir. I still have archive Maildirs with 3,000
or 5,000 messages in them.

It's not really specific to Maildirs, but many OSes and filesystems slow down
significantly when you have a large number of files in a single directory
(like Maildir/cur/), due to the linear-scan nature of directory access in most
filesystems. Some systems have implemented internal hashing and whatnot to
speed these operations up; patches have been posted to the linux-kernel
mailing list in the last few months showing ten- or hundredfold-increase in
speed in directories with 10,000 or more files.
Until you notice that it's slow, it's not a problem.
