Actually on the https://doc.dovecot.org/configuration_manual/fts/lucene/ site we can read about lucene fts plugin:

"This plugin is no longer maintained in Dovecot (as of 2.3+) and will be removed in the future."

Does anyone know about approximate EOL date for lucene plugin support in Dovecot?

Realistically ... many years ago.  There has been no maintenance or testing of the code for years now.
