first question that came to my mind you answered :) thanks!. i think its interesting a lot of stuff adheres to such ABIs etc. especially since they were conceived of quite a time ago, and often lean towards being compatible with older CPUs, where newer ones with more extended registers etc. might have features that could be used to improve this without making the structs shorter. I guess it's not super interesting to make software for specific hardware or hardware classes / generations as it'll be unusable on some machines, but having compilers etc. that _can_ produce it might be cool if you want to super optimise the code running on your system towards your systems's hardware features.
