We are talking about the large-scale commercial use of Dovecot + lucene as an FTS.
MIgration to SOLR is some kind of challenge that will take some time.
I'm trying to find out how much time I have.

On the one hand i would like to use only the newest version of Dovecot but on the other hand i'm not able to switch fts from lucene to solr in the near future

Why not assume that it could be removed at the next release and make
plans to migrate to a maintained FTS engine? If dovecot-fts-lucene is
currently working for you then dovecot-fts-flatcurve might be a good
alternative. (Another option is to not update. You might think that's
a bad idea, but with fts-lucene you already on something which is
outdated so that isn't new).
