Given discussions such as the one for -r341682 ( one message being
https://lists.freebsd.org/pipermail/svn-src-head/2018-December/120994.html ),
is a requirement for 64-bit atomics in order to support SMP
going to potentially eliminate platforms like the multi-processor
32-bit powerpc support (some old PowerMac models are examples)?
Should it be an example in WhatsGoing and a new ProjectPolicy?

(While I sometimes have access to a couple of such old PowerMacs and
experiment with FreeBSD on them, there is no reason FreeBSD should
consider that in any way. I'm just referencing an existing example
context.)


Separately:

Is there a fairly complete list of the Project Policies someplace?
Each possibly with the matching MD requirements implications (when
there are some)?
