[Dovecot] Concerns switching from Courier to Dovecot

I was considering replacing Courier-IMAP with dovecot in the future, but
have some concerns. I realize that some things simply haven't been
finished yet like quotas, but some other things may prevent me from using
dovecot as a drop in replacement in the future.

Subfolders have different names in the file system. A folder
(INBOX.subfolder) is named ".subfolder" in Courier, but "INBOX.subfolder"
in dovecot. I can't simply rename all the subfolders, because our
customers have direct access to the maildirs, and write to it directly
with procmail and mail clients like mutt.

Certain files have different names, but contain the same information.
For example, the subscription lists and UID files look the same to me
but have different names. I suppose they could be converted, but this
would make it difficult to run both IMAP servers side-by-side, which I'd
like to do until dovecot has all the features I need.

I also heard talk of the hierarchy separator being changed from "." to
"/".

Now, is it possible configuration options could be added to allow for
better Courier compatibility? I would be willing to help with this.

Thanks!
