Great, so let us advertise this kind of usage if needed.

Ah, thanks, I missed that bit.  I think now I see why the setup
described by Colin works as expected.

For me to recap, I see these use cases:

1.) Users install AUCTeX from ELPA:

    They don't have to do anything and can start using AUCTeX with:
    (use-package auctex ...)

2.) Users load AUCTeX from a local repo:

    They have to run make and then (let's skip the Info part for now):

    2a.)  Either use this in their init file:

          (use-package auctex
          :init
          (load "~/path/to/auctex/auctex-autoloads.el" nil t t))

    2b.)  or do:

          (use-package auctex
          :init
          (add-to-list 'load-path "~/path/to/auctex" t)
          (load "auctex.el" nil t t))

IIUC in 1.) and 2a.) the file auctex.el is more or less no-op, only in
2b.) it actually loads tex-site.el which then loads auctex-autoloads.el.

I briefly tested 2b.) by changing auctex.el with the code above, started
'emacs -Q', eval'ed the `use-package' form and opened a .tex file, it
seems to work and this is what I see in the `load-history':
