For sending, yes - but you also need to be comparing JIDs that you
receive, and you need to prep them before comparison.
Let's say you send an iq to=someunpreppedJID. You receive an iq
result, you check the ID matches - it does, you check the from matches
the to you sent - it doesn't, you bin the stanza as unsolicited.
Except had you prepped the to/from before comparison you'd have found
If clients don't prep there's the chance for assorted things to get
broken in interesting ways.
