STEP is capable of capturing what you describe, it is down to the "user group" of customers of the CAD vendors to ask for it to be implemented by each CAD system in terms of what they import and export.

We put in for some funding for the next edition of STEP AP242 for me to be able to work more closely with the user group to improve this area.

That's awesome! Yeah it seems strange to me that we don't have a standard way of tracking how a model is built up and parameterized (basically Fusion 360's history mode). I'd naively assumed that this was a solved problem in the CAD world - given the whole point of parametric CAD is to be able to easily tweak the distance between two points and have the whole model update.
