Sounds like a good direction to go, and I imagine it'd facilitate
building wrappers that extend GWL. One of the things I'd love to do
with GWL is to make it play well with git-annex, something that would
almost certainly be too specific for GWL itself. For example
* Make data caching git-annex aware. When deciding to recompute data
files, GWL avoids computing the hash of data files, using scripts as
the cheaper proxy, as you described in 87womnnjg0.fsf@elephly.net.
But if the user is tracking data files with git-annex, getting the
hash of data files becomes less expensive because we can ask
git-annex for the hash it has already computed.
* Support getting annex data files on demand (i.e. 'git annex get') if
they are needed as inputs.

For my personal use, I'd almost always want to pin an analysis workflow
at a certain Guix version, so making it easy to use inferiors in the
workflow would be great.

This is another one I'm especially excited about. Functionality-wise,
are you imagining essentially matching the options available for 'guix
environment --container ...'?
