Thanks for the review, Christoph. Unfortunately the gist of the message
got cut off:

Maybe that wasn't obvious from the first message. Is there any way we
can come up with a way to have versions of these functions that you
would be fine with exporting?
The point is that otherwise we would have to either duplicate the code
or come up with something way more complex. If you have any pointer that
would already help.
