This was indeed the case in the build I'd compiled for testing:

GNU Emacs 28.0.50 of 2021-09-29
Repository revision: b02a7ad2631b6ac3a95e53cb26a0aa1b1ab7e98a
Repository branch: master

I tested with a copy of so-long.el in which I renamed all of the
so-long-* symbols to sl-* and then configured the local variable
;; elisp-shorthands: (("sl-" . "so-long-"))

Loading the new sl.el confirmed that Emacs didn't recognise the
shorthand symbols generally.

(Until now I was under the impression that this was all part and
parcel of the shorthands feature, but it turns out that it's a bug.)
