Yes, I've read it and appreciate the detail.  However, it just doesn't
apply to my situation or what I think is typical for an office setting
where creating an account/password is a small part of user 
administration. If you apply disk quotas, a Maildir under their home
directory is automatically included.  A Cyrus mailbox is another step.
Backing up the home directories will include their mail folders.  Cyrus
mailboxes will be somewhere else.  Deleting a user account and home
directory also removes their Maildir mailbox. Removing a Cyrus mailbox
is a separate step.  When you replace the server, Maildirs come along
with the other contents of home directories.  And there's probably
more that I've missed.

Again, it is a 'user management' issue.  There are things that have
been running for years here out of procmail scripts. If the default
configuration for Cyrus doesn't keep them running, then it doesn't
help to talk about how easy the install is.

It is an administrator vs.user issue, not specific to any program.  If
you had existing users with .procmailrc files would you fix them,
let them break, or continue running something that just keeps working
as expected?
