Well, the package ’guix’ has changed 14 times over the past year.
Therefore, this D cannot be this package ’guix’, IMHO.

Maybe I have a bad practise but here my “guix pull” history:

--8<---------------cut here---------------start------------->8---
$ guix pull -l | grep Generation
Generation 1	nov. 17 2023 13:18:58
Generation 2	déc. 11 2023 10:55:51
Generation 3	févr. 02 2024 01:56:52
Generation 4	mars 25 2024 18:22:25
Generation 5	mai 13 2024 19:28:31	(current)
--8<---------------cut here---------------end--------------->8---

Therefore, I am not convinced that replacing "Computing Guix derivation"
(build-aux/build-self.scm) by the package ’guix’ would be robust enough.

(Assuming another package ’guix’, lighter e.g., without requiring the
test suite, etc.)

All that said, any experiment – even if it appears at first clunky – is
very welcome!  This part will be improved only if there is a collective
effort / discussion / try, IMHO, i.e., by challenging the status quo. :-)

Cheers,
simon
