SPEC_I_PT used to work with REGISTER AND IGNORE EXISTING KEY, but that
combination was removed by the REGISTER AND MOVE service action proposal
03-337 (apparently incompletely).  SPC-3 letter ballot comments to reinstate
it were rejected, saying a detailed proposal would be needed to make such a
change in SPC-4.
