Tony,
I suspect that this an obsolete design feature from the old "classic"
Europa, that had the bagage bay bulkhead at that position. When bonding
component together, you don't want a foam core at the bond-site - hence
the triangle (compare the angle of the foam with the angle of the
bulkhead). When the classic was developed into the XS and the bulkhead
moved back, this was never changed.
It does not constitute a weak point and I would not worry about it.
Adding more material will only add more weight.
