Right, in that case you can't use FS layout. But you could use e.g.
Maildir++ layout:

mail_location = mbox:~/mail:LAYOUT=maildir++

Then the mailboxes get created like:

~/mail/.sub
~/mail/.sub.box

This is a broken location setting. It's missing the mbox root directory.

It should be list=yes, otherwise mailboxes aren't visible to client.
Probably hidden=yes too so it won't confuse other clients.

Two namespaces can't have the same prefix. You commented out in the
first one, so that doesn't work. If you wanted Dovecot to somehow
automatically figure out what mailboxes are maildir and what are mboxes,
that's not possible yet.

There's no such thing as $u. I guess meant %u.
