As you say extruding a polygon on a plane has no issues with holes fully
cutting and where the cylinders are the same height with no vertical offset
that's trivial too (I just add "2" to the length).  The problem with the
hole lengths comes in when using hull to fill in the space between the
cylinders and the  cylinders are either different lengths, vertically
offset or both so that there are sloping sections between the two cylinders
meaning the holes are cutting through a sloping face so need to be longer
than their "parent" cylinder.
