Topological Naming Problem

Unless I missed it, the article doesn't answer the first question you'd ask: Why don't they just generate unique IDs for everything and use those internally, instead of names that get changed all the time?

I learned about it the hard way, ahah. Now I create intermediary planes for all distances and I extrude planes always with respect to those.

It's what caused me to move away from FreeCad to OnShape. Never had an issue in OnShape but got hit with it every time in FreeCad. The sad thing is that there was a fork for a long time which had addressed this problem, and added other nice enhancements as well, but they never merged that work. I guess every org has political problems and FreeCad is no exception.
