I'll respond to this part by part, but as you know the rule has been reverted so it changes this suggestion quite a bit anway.
Part 1 - Most of the APC redzone is wasteland anyway, we use parts for airdrops, there isn't really a valid reason to get rid of it.
Part 2 - Again the rule change comes in here, but there isn't really a need for "Advanced Cartels", the default Arma compounds are fairly balanced as it is, not really a need for more map objects
Part 3 - Sort of links to Part 2
TLDR; The rule has changed and there isn't really a need for a change to the current dynamic of cartels
