It's not that simple; Donenfeld wants to replace the whole LRNG with a new engine that uses simpler, more modern, and more secure/easier-to-analyze cryptography, and one of the roadblocks there is that swapping out the engine risks breaking bugs that userland relies on.
What kind of bugs are visible to userland? I would have thought a random number device would be the least likely thing to have upgrade problems like that: applications should not be able to assume anything at all since the output is literally random...
