So to summarize: This behavior is a side effect of how GNU tools
work. It is obvious to anyone who understands them. You don't want to
describe things that are obvious. I understand.

But I think many users don't have a clue about GNU build tools. They may
be puzzled by how pre-inst-env works. I think the footnote would be
helpful for them. I urge you to reconsider.

Yes, I saw you revamped Guix pull but I haven't actually used guix pull
in over a year.  I need to check the new one out.
