Nice, glad to see this feature put to good use.  :-)

Shouldn’t it be:

  (upstream-input
    (name dep)
    (downstream-name (php-package-name dep))
    (type …))

?

As a slight improvement, since the ‘inputs’ field of <upstream-source>
is delayed (wrapped in a promise, so that its computation only happens
when it’s needed), you could arrange to replace the ‘inputs’ variable
above like so:

  (define (dependency->input dependency type)
    (upstream-input …))

  (upstream-source
    ;; …
    (inputs (append (map (cut dependency->input <> 'regular) …)
                    (map (cut dependency->input <> 'native) …))))

I hope this makes sense.

Thanks!

Ludo’.
