I don't think we can drop features just because no use case presents itself for the moment. IME, a debugging aid could be of no use until you are in a situation where it is something to kill for. But we don't need to argue about this now, because the way we remove features from Emacs is by first declaring them obsolete, and keeping them like that for a few releases; we don't just drop them without a previous notice. So I'm okay with declaring this variable obsolete, and even removing its documentation from the manual, but we do need to restore the specbind call that was deleted. Philippe, can you do this, please? It should be done on the emacs-25 branch, since the specbind was deleted in 25.1. Thanks.
