Well, did you have any luck asking Asobo to add it.
How did that work out for you 
FSX initially was never going to have a Tower VIew, with a radar etc, but one of the Aces Team, (PR guy, not a developer, forgot his name) pushed for it, and it was because of him that FSX had the TOWER Mode.
It was very cool, and yes, missing in 202 (we will find out if added o 2024 in a few hours)
Many people enjoyed acting as ATC in FSX, especially when with groups in MP, that wanted a less formal ATC than Vatsim etc.
MS-MP used it, (Highly Modified) to run a comprehensive ATC system for FSX
Unfortunately, as it has not been mention in prior promotions for 2024, I very much doubt if we will see s similar TOWER MODE in 2024.
But we do have BATC, and the amazing AI Sayintentions.AI ATC systems, so all is not lost as far as better ATC is concerned going forward into 2024.
