As a side note, while ignoring the boundaries makes sense for comparison
operators, seg_union() and seg_intersect() need to do with them. That's
not documented anywhere, and their current behavior seems pretty
arbitrary. We haven't actually documented those functions at all, I
think they were added just for the GiST support and calling them
directly from SQL was an afterthought.

Applied to master and all stable branches, thanks!
