The "all other keys are ignored" is to be understood in the sense of
package-vc uses a subset of the keys that elpa-admin uses.  After
loading and initialising package-vc, you should in fact see a plist of
package specifications fetched from {Non,}GNU ELPA in
`package-vc--archive-spec-alist', which are used by package-vc if you
attempt to install a package using just a symbol.

Yes, exactly.

If you think it can be clarified, why not?
