I'm not surprised it doesn't work. We need to clearly define what
happens when you mix and match updates via SFA and PLCAPI,
but I'm not sure we want to invest the time in making it seamless
to move between the two.

That said, we certainly need to make sure there is a workable way
to change your keys.
