Yeah, famously there is no stable public driver API for Linux, which I believe was the motivation for Google’s Fuschia OS

So Linux is opinionated in both directions - towards user space and toward hardware - but in the opposite way

It's not just opinionation though. It's the kernel's leverage against the people who would keep their modules out of the git tree instead of contributing them. Those people literally get left behind and they are forced to pay maintainers to chase a continuously moving target. The solution to that is to contribute the code.
