Yeah, you’re basically betting that people will put a lot of effort in trying to out/optimize the hardware and perhaps to some degree the OS. Not a good bet.

When SMP first came out we had one large customer that wanted to manually handle scheduling themselves. That didn’t last long.

Effort? It's not like it's hard to map an SRAM chip to whatever address you want and expose it raw or as a block device. That's a 100 LOC kernel module.
