Here are practical issues that come to mind:
• It would only work for newer profiles, created after the feature has
been implemented (maybe that’s okay).
• The generated files might use APIs that, in the meantime, got
deprecated or changed somehow. This is in contrast with
‘--export-profile’, which interprets ‘manifest’ (a versioned file
format) and produces code that can use the API du jour.
• One would still have to learn about these two files, and pick the
right “manifest” file.
• For users of ‘-m my-manifest.scm’, we would need to store
‘my-manifest.scm’ as is instead of generating an approximation
thereof.
We already discussed these issues at length earlier. :-) Again, I agree
that following what we do with /run/current-system would be nice, but
the situation is different due to imperative operations.
Hmm, needs more thought…

Would be nice.
Thanks for your feedback!
