The content of nnml-directory is similar to a newsSPOOL - from which
Gnus historically has been (and is) able to read directly, when pointed
at it.

The manual says:

,----[ 6.3.13.11 Comparing Mail Back Ends - 
http://gnus.org/manual/gnus_202.html#SEC202 ]

| mail-splitting, due to the creation of lots of files, updates to the
| nnml active file, and additions to overview files on a per-message
