Right...

No.  Different files with similar names are created there.

new/, cur/, and tmp/ alone would be enough to provide the necessary
Gnus functionality.  nnmaildir maintains two additional sets of
information: NOV data and marks.  Storing NOV data speeds things up.
Storing marks adds flexibility when working with mailboxes from
outside Gnus.  Storing marks in a single file per group, as is done
with nnml and nnfolder (which I assume is what you were referring to
above), would also add flexibility, but not as much.  If we give up
the extra flexibility, what do we get in return?
