Currently, the result is `0` which is certainly correct for sufficiently
large values of the parameter. However, the rest of the asymptotics code
as I remember it does not really assume "sufficiently large values of the
parameter".

I think the result should be `O(0)`. Currently I am thinking about an
implementation of such a term and playing around a bit. If you want to get
this ticket to positive, then I would raise a NotImplementedError at the
moment. But give me a couple of days to figure out how `O(0)` would be
possible.
Best, Daniel
