current state of Cad/Cam software 2022, what works LinuxCNC etc

Umm. You do realize that RealThunder's changes fundamentally alter the basic structure of a FreeCAD project file right? They change the foundational separation of of GUI and application. Once you go down that path, you can't go back. I know (and trust) most of the core developers of FreeCAD. They aren't going slow because they're too conservative. They're doing it to avoid breaking everybody's models.. Permanently. Even RealThunder agrees that this has to be done carefully and incrementally.
But if you know better how to get the good parts of the RT's branch merged, why aren't you helping?

sometimes, growth, requires pain and suffering, the models will break eventually anyway, just get it over with

I have abandoned two CAD packages at the point that my models no longer worked. At that point you might as well move on, and I did. 

Alienating users isn't a good way to build you user base. 

generally i agree, bit they can leave the existing branch operational and useable, just stop developing it.

the thing is, that no matter what, the models are going to break, it is a unavoidable side effect of the changes to fix face naming issues. a poor decision was made at the beginning of the development of freecad, and now, that decision is here to be dealt with. 

and honestly, it's jist a model, it can always be redrawn

start freecad r2

oh please, enlighten me.

the toponamng issue is a problem that fundamentally breaks freecad.

having to work around it is a no go for professional use.

no other cad software in the commercial market has this problem. swallow the pill make the break be done with it
