`locate-file` is a function looks for files with a given set of
extensions through path.  That's it.  Nothing specific to ELisp files.
E.g. it's used in `executable-find`.

The existence of `.eln` should have no bearing on this.

It can affect the ELisp-specific code (such as `load` or
`find-library`), which may indeed use `locate-file` internally, but it
should not affect `locate-file` itself.

That's just what my understanding of the code tells me.

Notice that I did not install it on `emacs-28` nor asked to do that.
I only mention it as a way to say that I consider it fixes a regression
in Emacs-28, rather than being a "backward-incompatible change".
