The strange thing is that they bothered removing the identifier that
had already been issued; there must have been a compelling reason
to make a change beyond the fact it didn't meet the criteria for a
new 3 letter.


I'm not sure I follow you. Many airports have had their identifiers changed
when they no longer met the criteria for the previous identifier. That
seems to be the case with Drummond Airport.



I wouldn't be surprised if KDRU shows up somewhere else in
the next few years.


I think that unlikely. Remember, the identifier for Drummond VOR is still
DRU, only the airport identifier was changed.
