Answering the second part first, yes, it's an open enhancement request 
(http://bugzilla.mindrot.org/show_bug.cgi?id=983).

Going back to the first part: while requiring both password and 
public-key would probably improve security, personally I think the 
private key is another instance of "something you know" (although with 
the useful property of being able to prove you know it without 
disclosing it) since it can be copied, printed out, emailed...

     Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
