Aha, it all becomes clear. This seems to be a fundamental
misunderstanding and perhaps documentation "bug" on the part of cPanel.
They are clearly making the option available without, perhaps, fully
understanding how the option works.

I would not expect there to be. cPanel is a "self-contained" hosting
platform which makes very heavy customisations to a lot of packages
(Apache httpd, Exim, PHP and so on) but rarely goes upstream to discuss
things (in my experience).

That could have been avoided if you'd mentioned cPanel in your initial
report. I can guarantee, absolutely, that they won't be providing the
default config file - their raison d'etre is to provide a buffer between
you, the user, and the underlying components so you can manage your
hosting system via a web interface.

Unfortunately we spend a lot of time answering questions regarding
various Exim switches and options where it becomes very obvious that the
person raising the question has not read the docs (which is poor form).
This is similar to the "don't press this button" psychological
experiment; in your case you aren't really to blame, as such, because
you couldn't see the button you were pressing until it was too late. You
then lifted the covers (cPanel) to see what you were leaning on (the
Exim config)...

I'll quit with the poor analogy now :)

I think you can take it back to the cPanel maintainers, in that case.
They will need to improve their docs. Feel free to pass on the proposed
warning I posted earlier.
