I have never analyzed this with free body diagrams or whatever, but I'm pretty sure that the more accurately the cartridge is aligned the less those skating force magnitudes get.There's simply no way this is the case - the change in the skating force vectors is miniscule with changes in things like overhang, azimuth, and VTA. Now VTF, of course. But I absolutely agree with you in the sense that the more precisely the cartridge is aligned . . . the better the system performance, in virtually every aspect.
I have NEVER experienced a changed in the perceived dynamics when adjusting a well-designed (repeatable) anti-skating compensation mechanism, on a well-matched arm/cartridge combination. With some of the fishing-line things, I've experienced all manner of weird side-effects.
I HAVE experienced what you describe as "crushing the dynamics", but I associate this specifically with a arm/cartridge combinations with very low resonant frequencies, i.e. 6-8 Hz. I will admit that I have never really tried to tweek such a combination to sonic perfection, and I can conceive of how anti-skating adjustment could interact differently in these situations than in my experience. But I've always found that I prefer the performance of arm/cartrige combinations that resonate at somewhat higher frequencies, and tonearms with very accurate, repeatable VTF and anti-skating adjustments. And with these, my measured data the my listening experiences have a good correlation.
