So the goal is to make things slightly more concise than:

  (profile (content (packages->manifest (list …))))

right?

We don’t have syntactic sugar like this elsewhere, and I would prefer to
remain consistent here.  However, if that helps, we could have a
procedure, like:

  (define (packages->profile name packages)
    (profile (name name) …))

Thoughts?
