📚 Convention to differentiate between user and internal API

[s-weigand]

Version information

All

Describe the issue

If we have a way to differentiate between user API and internal API users shouldn't touch (use on own risk), we could quickly determine if we need proper deprecation to preserve the current behavior or if it is ok to change it.

Expected documentation

Something like Internal API subject to changes, use on own risk!

or

We have some kind of allow list with all functions for the user API.

Additional context

For #851 we agreed that Problem isn't part of the official user API.
