Correct, because local_parts checks *this* local part at RCPT time; at
DATA time there may be more than one local part.

That still won't help. What do you do when a message is addressed to two
users, one of whom is on the list and one not?

No, because there may be more than one recipient.

Impossible. I cannot see a logical way to do this. The only choice you
have at DATA time is to return "yes" or "no". There is no way of saying
"yes for these recipients only". (LMTP has introduced this facility, of
course, for similar reasons. However, LMTP isn't what is used over the
Internet.)
