I'd definitely love to be able to get the proper dsync migration working as I have some clients who use POP3 and others who use IMAP and I want to make this seamless for all if possible.

-c is a global option for all dovecot binaries, including doveadm. I guess all the global options should be included in all the man pages..

I'm not sure what you mean here. It's possible to switch between namespaces on the fly without losing anything (besides clients seeing them differently).
