Correct: the specification changed under us, which rendered that

That would be an ABI break, which we strive to avoid. However, the next
release of Hubbub already breaks the ABI in other areas, so I'm inclined
to take the opportunity to remove that treebuilder callback entry.
Of course, it might resurface later, should we ever get around to
bringing Hubbub's implementation back in line with the specification.
Somewhat embarrassingly, it's nearly 5 years out of date.
