Not at all, no, I must have been unclear somewhere (maybe because
there's "autoload" as in using a `;;;###autoload` cookie somewhere, and
"autoload" as in having help-fns.el `load`ing a file in response to
something the user did in order to try and get more information about
the contents in that file).

I was saying that we can avoid the discrepancy either by:
- Change `help-enable-autoload` to also cause `help-fns.el` to (auto)load
  `face-remap.el` when you do `C-h f global-text-scale-adjust RET`
- To try and figure out why `C-h f text-scale-adjust RET`
  causes `help-fns.el` to (auto)load `face-remap.el` (presumably
  conditioned on `help-enable-completion-autoload`) and change it so
  it behaves like `C-h f global-text-scale-adjust RET` instead.
