The database does distinguish between canceled and expired. Unfortunately,
this doesn't help. Expirations occur due to lack of action by the ham at
renewal time but the ham can be living or dead. Cancellations occur due to
action on the part of someone but that action can be by the ham, next of kin
if deceased, or the FCC as a penalty.

Yep - and they're relatively few.

I don't think the SK list would necessarily be that accurate. Someone has
to send them the info before they can publish it.

Because of some really poor attempts at practical jokes, both ARRL and FCC
require some particular paperwork to consider a ham truly SK. Thus a
cancellation and/or SK notice may appear quite a while after the ham has gone
to the Big Hamshack.
