I disagree, but I guess you would have expected that. But this is not the 
issue.

What I would like to point out that more and more folks change to 
getrandom(2). As this call will now unblock much later in the boot cycle, 
these systems see a significant departure from the current system behavior.

E.g. an sshd using getrandom(2) would be ready shortly after the boot finishes 
as of now. Now it can be a matter minutes before it responds. Thus, is such 
change in the kernel behavior something for stable?
