FWIW, I know this bug report and the linked discussions. That's why I don't
think that this will change upstream anytime soon.

Ok, I think I got your point, but I'm not sure I agree entirely.
The if-down.d hooks were written under the premise that the network is still up,
which it currently in NM's case is not.
But to have a better answer to this question, I guess one would have to analyze
the existing ifupdown hooks in Debian and check, what they are actually doing in
if-down.d resp. if-post-down.d
