Query aircraft.cfgs icao_type_designator or flightplan destination via SimConnect

Hi guys, currently it seems we can still only SimConnect query ATC MODEL which
gets the atc_model from the aircraft.cfg? Is there a way planned to also query
the icao_type_designator from that same file? In addition, I have not yet
found a way to get the flightplan destination ICAO, if the user has loaded up
a flightplan. While the SDK shows a ton of quite new ATC variables like ATC
IFR FP TO REQUEST , the destination does not seem to be a part of that.

All icao* parameters are not reachable as Simvars:

icao_airline
icao_type_designator
icao_manufacturer
icao_model
icao_engine_type
icao_engine_count
icao_WTC
icao_generic

In general, it should be possible to access programmatically to any variable that might be found in the various .CFG files.

This is even more important now, since the aircraft.cfg file might not even be accessible when streamed.
