There's currently (2.16) no way that I can tell to produce

UnexpandedTargets

from an arbitrary list of targets. Would it be possible to reproduce that with a rule? Say by finding target owners and deduplicating? Context: I'm trying to hack to combine

peek

and

dependees --closed --transitive

into a single goal

in a rule you should be able to do:

await Get(UnexpandedTargets, Addresses([t.address for t in targets]))

you can? I just took this output as meaning the rule was only available as an intrinsic

❯ pants help-advanced UnexpandedTargets

`pants.engine.target.UnexpandedTargets` api type
------------------------------------------------

Like `Targets`, but will not replace target generators with their generated targets (e.g.
replace `python_sources` "BUILD targets" with generated `python_source` "file targets").

hmm… the returned by 0 rules is plain wrong… will need to look into that. https://github.com/pantsbuild/pants/blob/361a665a8b2ec471dec82907f63e0f9d40d7ccca/src/python/pants/engine/internals/graph.py#L109-L132
