Moving it to user space is just generally stupid.

Often, the random stuff comes from chipsets, not the CPU itself. Not
user-accessible at all, and even if it were, it would be a bad idea to
have user space do things the kernel does normally ("what northbridge do I
have").

There may be use for a user-level library that handles the native CPU
instructions for high performance, but that in no way negates the reason
why /dev/random and friends exist in the first place.
