Considering "large" data, the questions are:
How to compute the hash?
Does Berlin have a copy of large data set?

I know that it was not your initial intention with 'copy-build-sytem'. :-)
You want something like that:
--8<---------------cut here---------------start------------->8---
(define-public debian-archive-keyring
(package
(name "debian-archive-keyring")
(version "2019.1")
(source ...)
(build-system copy-build-system)
(arguments
'(#:install-plan
(lambda* (#:key outputs #:allow-other-keys)
(let* ((out (assoc-ref outputs "out"))
(apt (string-append out "/etc/apt/trusted.gpg.d/"))
(key (string-append out "/share/keyrings/")))
(install-file "keyrings/debian-archive-keyring.gpg" key)
(install-file "keyrings/debian-archive-removed-keys.gpg" key)
(for-each (lambda (file)
(install-file file apt))
(find-files "trusted.gpg" "\\.gpg$")))
#t)))))
--8<---------------cut here---------------end--------------->8---
instead of the current:
--8<---------------cut here---------------start------------->8---
(build-system gnu-build-system)
(arguments
'(#:test-target "verify-results"
#:parallel-build? #f ; has race conditions
#:phases
(modify-phases %standard-phases
(delete 'configure) ; no configure script
(replace 'install
--8<---------------cut here---------------end--------------->8---
I agree that it is a good idea.
The aim of my comment was:
1. Point out a previous discussion about the packages of data only;
which is what we are talking about, right?
2. Discuss if your proposal can fit some data distribution issue;
discussed earlier at point 1..
Cheers,
