I think that one of the key problems with the 432 was that they skipped talking to the assembly language programmers!
The 432 omitted stuff that most assembly language would deem essential (eg registers where I think an assembly language expert would have immediately focused on performance impact) and I think assembly language programming of the 432 would not be fun at all.
Agree 100% that upgrading it would have been a nightmare. I suspect that they simply didn’t have the bandwidth to think about v2.
