[Dovecot] fts plugin - purpose of get_last_uid() ?

[Per Jessen]

It looks like the uid returned is only used as an indication of whether
the maildir is fully indexed or not, is that correct?  

In my setup, the index is built externally and will _always_ be
up-to-date.  Getting the last uid would mean running a query, which,
whilst inexpensive, seems unnecessary if my understanding of the
purpose of get_last_uid() is correct.
