I thought it was so that it will point to the correct user line (or
tend to point there). So stacklevel=2 for exposed and higher for
private (python) functions IIRC.
As for developers, I would hope they are OK with (and know how to)
turning the warning into an error.

Not sure we discussed it much, I seem to have a vague memory of asking
if we are sure this is what we want and at least Ralf agreeing. Also I
don't know how consistent it is overall.
