No, this would not be right.  If you install a newer version of a
package that comes with Emacs (e.g. Tramp), you want Emacs to pick its
documentation from /usr/share/info and *not* from
/usr/share/info/emacs-MAJOR.  See the docstring for
Info-directory-list:

,----
| When `Info-directory-list' is initialized from the value of
| `Info-default-directory-list', and Emacs is installed in one of the
| standard directories, the directory of Info files that come with Emacs
| is put last (so that local Info files override standard ones).

I think that would be TRT, since the elisp-manual is specific to
Emacs 21.  And at least the `info' program has no problem finding
files in subdirectories.  Reassigning this bug to the elisp-manual
package,
