What does this warning mean?
It flags the line which contains a reference to another included object.
Have I missed a list of warnings somewhere?
thanks

That you had splitting of unions on but are also having a bounded_by in the
union. What it implies is that the bounded_by has been removed because it
is redundant.

Shouldn't I bother with bounding boxes any more?

You generally will only get an improvement over the automatic bounding
with CSG difference or intersection...you can also get an improvement in
certain cases with a large number of objects regularly spaced in a
union, but that's a pretty special case.
In your case, because you had splitting of unions on, the bounding box
was useless because the union was split into several separate objects.

User-specified bounding boxes have been more or less obsolete since
POV-Ray 3.0.
Only in certain cases a user-specified bounding box gives a better
result than the automatically calculated one (these cases include certain
CSG operations and blobs).
