It could probably use lib-dict instead. I was actually originally thinking about using METADATA plugin as storage for these, but just configuring a lib-dict backend would probably be fine too. Like:

urlauth_dict = file:~/Maildir/urlauthkeys

or

urlauth_dict = proxy::urlauth
dict {
  urlauth = pgsql:/etc/dovecot-dict-sql.conf
}
