Ardupilot team has stopped firmware development for APM1/APM2 boards in 2015. I wouldn't advise buying it now with intent to work on stabilization firmware.

Yeah but stabilisation doesn't change over time, for the most part it still remains PID based. 8-bit MCUs are so under-utilised & 32-bit processors are simply an overkill & barrier to people getting started.

The attitude stabilization- yes, I would agree.

But the development mostly seems to concentrate around higher level, position and navigation controllers and there is a lot of complex floating point math going on there.
