Thanks. It perfectly answer to my question. :-)

I am confused. The 'specification->package' returns a regular
package, right?. And then,
--8<---------------cut here---------------start------------->8---
(define gnutls
(specification->package "gnutls"))
(define dependencies
(append-map transitive-package-dependencies
(list guile-gcrypt gnutls guile-git guile-avahi
guile-json guile-semver guile-ssh guile-sqlite3
guile-zlib guile-lzlib guile-zstd)))
--8<---------------cut here---------------end--------------->8---
So here, a transformation could be applied. For example, build all
the dependencies without testing them; at the 'define gnutls' (&co)
step or in the map. Why not?
Well, just to be able to travel back in time if some expiration changed.
Cheers,
