It does if one's Contacts app stores Signal contact information for one's contacts; then one could simply query using non-Signal information as the key (e.g. one could ask, 'give me Signal contact information for tel:+15551212, mailto:fizzbuzz@barquux.org and http://plus.google.com/SomeUserName' http://plus.google.com/SomeUserName').

That doesn't seem like a very good tradeoff because then it requires Signal to store/compare _more_ personally identifying information (though I guess you could make many of those things pseudo-anonymous).

Actually, it's possible to do even better that that: one can execute a private set intersection protocol so that you & each of your contacts can discover mutual contacts without revealing others. Signal aren't required to store any personally identifying information: they choose to do so.
