Add to this is that the entire mozilla libraries are still

Just tried it by catenating many folders into a single folder
exceeding 4GB (11.8 GB, to be exact).
Yes, and Maildir is the intended solution to that limit, because
compacting mbox files is an expensive operation,
Maildir is really a solution to lockless parallel mail folder access. It does
store things as inidivdual messages, one per file, and I use it in my larger
more active mail folders. My less active folders (receiving filed email, but
accessed in frequently) are mboxen: it is more compact and cheaper to in
storage and filesystems.
and incremental backup of mbox files is difficult or impossible depending on
your backup software. [...]
In my world mboxen are easier to back up in some ways, more expensive in
others. I backup with rsync and date stampted hardlinked backup trees:
unchanges files get hardlinked to the next tree. In this scheme a Maildir only
makes new files for the new messages, which is a win in storage. But a larger
maildir is very slow to scan, especially on a physical disc. By comparison, an
mbox makes a whole new copy of the mbox if it gets changed, but it is very
cheaper to scan (one file).
I'm still amazed that TB doesn't let you use Maildirs; they're hardly
difficult.
