Except no one's asking them to "gimp" the available models. People are asking for more options in the high performance space. If Apple doesn't make it, you can't simply go to HP and get it there. You have no choice. It's either run out of memory, or abandon your whole OS and software stack.
Apple is forcing a segment of it's customers to abandon it's ecosystem to continue getting their work done . Their lack of reassuring response insinuates that macOS is a non-scalable toy platform.
I have no horses in this race myself, but if I had hundreds+ invested in Mac software and accessories, with no machines available on the market to handle my workload, I would be pretty bent.
