Yes. However...

1) I'm not sure the v3 snmptrap&d code in the 4.1.2 release was correct (I
   don't think it is).

2) The trap code in 4.2.pre1 release should be.

3) The createUser line for inform notifications is as you'd expect.

4) For snmpv3 traps (unacknowledged), however, the user has to be
   created using the -e ENGINEID switch to createUser (which may not
   be documented).  The ENGINEID must be the engineid of the remote
   entity (the one sending the traps) instead of the local one (the
   one receiving the traps).  So, to send a v3 trap (as an example,
   I'm picking 0x001122 as a engineid):

   snmptrapd.conf:
     createUser -e 0x001122 user MD5 PASSPHRASE

   snmptrap -v 3 -u user -a MD5 -A PASSPHRASE -e 0x001122 localhost ...
