Ehm, I think you're not right, no

Software packages don't need to be expressed as files (.deb, .tar, .rmp or
any other format)

That's a convention, not a necessity

mainstream Linux distributions adopt such a convention

Others do not

As an analogy, If you say that packages are .deb files, it's as if you're
saying that a document is the paper it's printed on

So what would be the relationship between a file representing such document
and the papers that can be printed by it ?

Some will say that the hand signed paper is "the document"

Others will say that the LibreOffice file is the document

Guix doesn't release .deb or .rpm files for packages, no

but that's not "bypassing"

As long as distributing the file for a document is not bypassing the
distribution of printed copies

Guix is ensuring that that the binary bits belonging to a package (produced
by compilig its source code) it runs are the same on everymachine that
built
 the source with the same Guix recipe

And that's as an explicit producton of packages as I can think of

The idea that if there are no .deb files than the process is not explicit
is, in my opinion, not correct

The manual doesn't mention files and file formats because it doesn't assume
that software packages and files are identified

Binary files are a support, as paper id for documents

But the packages exist independently of supports (as documents do)

Hope this helps
