Key phrase, in main:
# For full debugger support use (turn off in stable branch):
Most recently (12th August) for amd64, a main view of the
twelve options that are _not always_ needed:
<https://github.com/freebsd/freebsd-src/blob/6a70a0c8bfa6fe8a2739527e5c822aec985e83e9/sys/amd64/conf/GENERIC#L96-L108>
So, for example, in stable/13 for amd64 we see the
two options, alone, that are _always_ needed:
<https://github.com/freebsd/freebsd-src/blob/0ca1220443695c79849bf0807306d0864acbabb9/sys/amd64/conf/GENERIC#L92-L94>
options KDB # Enable kernel debugger support.
options KDB_TRACE # Print a stack trace for a panic.

Notes to self
=============
After not easily finding a GitHub method to compare the same file in two
branches, I took a hint from <https://stackoverflow.com/a/59315113/38108> for a
web-based view of differences. Then, taking a hint from
<https://juplo.de/compare-two-files-in-different-branches-with-git/>:
git -C /usr/src diff remotes/origin/main:sys/amd64/conf/GENERIC
remotes/origin/stable/13:sys/amd64/conf/GENERIC | less
Context (my configuration):
% git -C /usr/src config --get remote.origin.url
https://github.com/grahamperrin/freebsd-src.git
% git -C /usr/src config --get remote.upstream.url
https://github.com/freebsd/freebsd-src.git
