Call signs do not match the aircraft

I notice that the call signs constantly do not match the actual aircraft. For example, Speedbird 2567 might be assigned to a Cessna, which spoils the immersion somewhat.

Can anyone please confirm that this (and any other flaws) are actively being worked on?

Compared with FSX, I am certainly impressed with the enhanced graphics, the live weather, and the live traffic, but I am underwhelmed & deflated by the ATC which actually seems worse; or the wrongly assigned callsigns I’m describing above, or the road traffic driving in some ridiculous places.

It would just be reassuring to know these things are actually going to be addressed.
