Fundamentally the problem I have with it is that getrandom must always succeed; applications cannot realistically be expected to recover from failure.
The current patch is the consensus which emerged after the first patches. In particular, you wrote a while back, “I think it would be better to expose getrandom() as a completely unadorned syscall.”
As a result of this community-support decision, ENOSYS due to lack of kernel support is always a possibility. I think this was pretty clear at the time, when the emulation based on device nodes was rejected.
