[Dovecot] status & use-case of fts_solr?

[PGNet Dev]

i've deployed a Solr server, and setup Dovecot for *both* squat & solr FTS.

iiuc, reading at,

 http://wiki.dovecot.org/Plugins/FTS
 http://wiki.dovecot.org/Plugins/FTS/Solr

as of dovecot v1.1.2, squat's required for IMAP compliance; solr
search breaks it.  is that still the case in v1.2?  Is IMAP-compliant
Solr search possible? planned?

if the goal is fast, indexed FTS of dovecot IMAP stores from within a
MUA, is fts_solr even helpful? or is it targeted for web interfaces to
search ... ?

thanks.
