What about ‘--list-dependencies’, for clarity and symmetry with
‘--list-dependents’?
Thanks,

It was originally '--list-recursive' but Bavier suggested
'--list-transitive' so it would match 'guix build --sources=transitive'
If it's too close to '--list-dependents' then I'm worried people could
look at it and ask 'packages FOO is dependent on or packages that are
dependent on FOO?'

Good point. I do feel like ‘--list-dependencies’ is clearer though.
With ‘list-transitive’, since “transitive” is an adjective, I first
wondered: transitive what?
What do people think?
Thanks,
Ludo’.

I pondered this a bit.
What about evolving our terminology as if we talk about the graph
produced by "guix graph"?
That means we have only 2 directions. Upwards: 'packages that are
dependent on FOO'
Downwards: 'packages FOO is dependent on'
This could give us the following terms:
X is an upwards dependency to Y.
FOO is a downward dependency of BAR.
=>
--list-upwards-dependencies
--list-downwards-dependencies
Furthermore we could create words to describe packages with many/few
dependencies:
Package X is a heavy root with 120 upward links.
We could define a scale and make our commands output it consistently:
- light root <=50 upward links
- medium root >50<=100 upward links
- heavy root >100<=500 upward links
- very heavy root >500<=1000 upward links
- extremely heavy root >1000 upward links
(The numbers above are just an example)
With npm-packages we could say:
Package X is a heavy root with 3 versions in use.
Package Y is a light root with only the latest in use.
(In npm a package can appear multiple times as dependency to
dependencies and sometimes in different versions meaning we have to
package it multiple versions of some packages.)
Thoughts?

Yes, I’ve been wanting something like this, but IIRC the current (guix
graph) implementation turned out to be inefficient to compute
upward/downward rank for a large number of nodes.
