Earlier I thought bullseye was some sort of idiom for Buster going live.
Color me ignorant. 

But concerning the currently proposed workaround for x86 CPU's (from
which I cannot "benefit," apparently), it's edifying to note what Ted
himself said about his own patch:

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=39a8883a2b989d1d21bd8dd99f5557f0c5e89694

 random: add a config option to trust the CPU's hwrng

 This gives the user building their own kernel (or a Linux distribution)
 the option of deciding whether or not to trust the CPU's hardware
 random number generator (e.g., RDRAND for x86 CPU's) as being correctly
 implemented and not having a back door introduced (perhaps courtesy of
 a Nation State's law enforcement or intelligence agencies).

 This will prevent getrandom(2) from blocking, if there is a
 willingness to trust the CPU manufacturer.

 Signed-off-by: Theodore Ts'o <tytso@mit.edu>

So Debian Buster, as it now stands and I understand it, trusts in the
correctness of the hardware random number generator, as well as in the
absence of any back door that might compromise it, universally and
without qualification, of every Debian Buster user's x86 cpu (default
kernel command line CONFIG_RANDOM_TRUST_CPU), in the name of security.

That's a safer solution than installing haveged? 

I know, I know, I can use any kernel command line I want. I could switch
to another distribution without these problems. I could go fuck myself.
But as an innate altruist (just kidding), I'm wondering whether the
regular user is aware of the implications of all this. What about people
in Nation States ...  Well, you get the idea.
