Daniel Mendler confirmed that recursive templates were not supported,
hence I cannot further improve snippets.
I've sent an updated patch with "-build-system" added only once at the
end.

Waiting for them to be adopted ;)

PS : it would be great to add a "snippets" output to the guix package,
so that one can use (file-append guix:snippets "/tempel/") to
include them in a guix home configuration.
