I think we should really focus on individual use cases and see how to
best address them.  For example there’s
<> that we could revisit now that we
have provenance metadata and inferiors.  There’s also ‘guix size’, ‘guix
refresh -l’, and ‘guix graph --path’.

Perhaps we could have the backend you propose with the name ‘plain-flat’
(or similar), but I agree with Ricardo that it seems misplaced given
that it doesn’t show edges.
