From my opinion, a complete subcommand for only one use case does not
seem the right thing.  Instead, IMHO, it would be better to have an
extension for that.

Because once we introduce a subcommand, it is hard to change (see
'guix environment') and since Guix provides this great extension
mechanism, I think it is the path for this kind of niche use cases:
start with an extension and depending on the "popularity" and interest
then upstream.

Well, if you think this feature is great to have in Guix proper,
personally I would find more coherent:

    guix package --create-manifest a b c --transform=whatever=else >
manifest.scm


Cheers,
simon
