I think the comparison is very apt. Practical APS is going to require a full sphere LPI radar of some sort. Given you already have to build that, it's logical to leverage it as a sensor for sensor fusion in general. Same goes with IR, both distributed aperture systems and telescope/periscope. EW equipment is going to require antenna apertures that can cover DC to 6ghz. If you gotta build those might as well aggregate all the needs into a common set of apertures. The logic here is straightforward, and it does directly lead to thinking of future MBTs as like the mini land version of multi role naval frigates, imo.
