Hmm. This isn't really a problem. Perhaps I should even hide this error
message.

This is a problem. Dovecot must be able to create dovecot-uidlist file.
You could place all the control files to a different directory though,
for example:

mail_location = maildir:~/Maildir:CONTROL=~/Maildir/dovecot:INDEX=~/Maildir/dovecot

Indexes don't really matter, but performance is better if they exist.

Anyway if you already have users using the mails, you should copy/move
all the dovecot* files to ~/Maildir/dovecot/ under the correct
directories. dovecot-uidlist and dovecot-keywords most importantly,
otherwise the users will redownload all their mails and lose any message
keywords they've set.
