Nothing really prevents from adding that very easily .. I guess it would need a new setting, which is always the most annoying part of small changes. :) I think it would have to have a setting equivalent to doveadm index -n parameter, which allows indexing most users, except those who pretty much never read their emails. So with doveadm index -n 1000 you could set that if the mailbox's \Recent count is over 1000, don't index the mailbox. So .. hmm. I guess two settings would be cleaner:

plugin {
  fts_autoindex = yes
  fts_autoindex_max_recent = 1000
}

Or maybe there's a better name than "autoindex" for this feature. SEARCH always autoindexes anyway.

No, fts-lucene and fts-solr are separate backends. But I do have some small plans to add a few more features to fts-solr.
