We could, yes. It should not be a valid domain name, for example. But whatever
magic cookie we came up with, we would need to document it so that user code can
avoid displaying it. And to avoid typos it would be better to make it a named
constant. And we would need to do something similar, with different named
constants, for similar issues such as emacs-build-time. And we would never
eliminate the possibility that someone (if only to be contrary, e.g., because
they are attacking Emacs) would use the magic-cookie as a host name. All in all,
it would be a relatively complicated solution to what should be a simple problem.

My comment’s “in the sense” referred to the sense of its previous paragraph (not
quoted above) which talked about deterministic builds; it did not refer to
building Emacs in general. In some cases it can be useful to have the build
hostname embedded in the executable even at the cost of deterministic builds.
However, many people (including myself) prefer deterministic builds, and for
them embedding the build hostname is counterproductive, and that is why it is
useful to have an option to suppress it.

Nothing in my commentary was intended to exhibit any disrespect. It was intended
to be purely technical commentary. If it seemed otherwise, I apologize.

I do not see what I am ducking here. Surely you are not advocating leaving the
behavior undocumented. Are you objecting to the convention of using nil to
represent lack of information? If so, how about if we use some other symbol,
such as ‘unknown’? Although that would be a bit more of a pain to document and
use, it would also be OK and for the reasons discussed above would be better
than a magic-cookie string.
