Pretty much - and the "patch" would be super-invasive even if someone

Yes - we use cyrus-sasl as shipped by our vendor (Debian in our case).
You will need the cyrus-sasl-devel package (or whatever it's called).
Or talk to Jeroen about pre-compiled Cyrus RPMs.  He probably has some.

Everything should migrate itself automatically.  It will be VERY slow for
a while while it basically does a reconstruct of each mailbox first time
you open it to upgrade some of the datastructures.
