Because you answered their question, I'm hoping you can answer my question.
How is there any overlap in the devices that can't have something clever figured out and devices that could possibly see an update to their kernel code?
Kernel side something clever almost certainly will be figured out eventually just not in time for the 5.18 release (or probably following release either realistically). User space side it doesn't matter if there is an absolutely trivial clever fix available you can't just break it without extremely good reason.
Note: Extremely good reason for breaking userspace is along the lines of "/dev/random has been found to be insecure causing mass security mayhem" not "man I'd really like to ignore the 0.01% of users this would cause an issue for so I can get my patch in faster".
