Well, Gnus also comes with nnmaildir, which does what you want.  So
the user has the choice.

Maybe some users want to store messages in nnfolder but the MTA
delivers to a maildir.

Yes and no.  mail-sources always needs an intermediate storage: it
copies the messages from the spots specified in mail-sources to temp
files, then from there into the groups.  This avoids problems with
locking.  As mail-sources works for many types of sources, it uses
the same mechanism always, to avoid the locking problems.
