Agreed.  How about making these two changes:

  1. Include (gnu packages) in the default evaluation environment of
     manifests.

  2. (define (package-specifications->manifest specs)
       (packages->manifest (map (compose list specification->package+output)
                           specs)))

Thoughts?

(To be clear, my suggestion is to do this in addition to adding support
for a new format.)
