cur/ only changes when the client selects the folder, because the
contents of new/ is moved to cur/. since it's Dovecot doing this, it
knows what has been updated.

I use procmail, too, and both it and Dovecot work as expected.

no, it works regardless of whether the indexes are up-to-date or not.
if they are not, Dovecot updates them. and I'd guess that the majority
of Dovecot users don't use dovecot-lda.
