Hey,
The SRS IFF integration is on the to-do list, it should come at some point.
The N/A never had L16 datalink (only Radar variants had it around 2016-2018 ish), If you want to know where your mates are you'll have to do it the old fashion way with a bullseye card.
The RWR options are also on the list, but don't idealise what they'll bring you, on public servers with 10097867789900 sam stations it will either look crowded as f.u.c.k (trying to get around the new profanity filter) or you'll have so much emitters turned towards you that the filtering options will actually reduce your SA. Will still be nice to have them.
Cheers, AJ
