Then please put that guideline somewhere.  (Currently, the doc string mentions
only autoloaded functions in newcomment.el.)

IOW, I've gotten the message, but this is not obvious, so please help other
users by pointing this out somewhere.

I see.  Is this what is done whenever something that was formerly preloaded gets
moved to a library that is not preloaded?

To be clear, it doesn't bother me that we autoload something that you might
consider extra.  I'm just pointing this out as an apparent exception - a place
where you might want to take a second look (which you've now done).
