You’re not missing anything: it’s a longstanding source of confusion
that these ‘manifest’ files are not like the ‘manifest.scm’ files.
These ‘manifest’ files are meant for internal consumption.
I think Pierre Neidhardt started looking at ways to address it from
different angles, but that hasn’t materialized yet. One thing we
discussed was to add an ‘--export-manifest’ (or similar) option that
would export a ‘manifest.scm’ file for a profile, where the
‘manifest.scm’ file could be an approximation of what the profile
contains, in some cases.

Yup!
Thanks,
