Quite agreed. The FAA moves in mysterious ways!
Even among themselves.
The POI's of both have deferred to Washington on the issue and are awaiting it's response. That has probably already been bought and paid for so to speak.
As I understand, the POI's of both certificates want to be the boss of the other or the remaining POI of the combined mess.
The manuals have been merged (for the worse in my opinion). Little more is needed except Washington's approval and the pilot contract merger.
