Yes, NM dispatches its down event after the interface is down.
01ifupdown currently maps that to pre-down, which is broken.
You are just arguing from another pov. Your point is, that NM's down event
should rather be called post-down.
Doesn't change the fact though, that the current mapping is incorrect.

Not exactly sure what you mean by that. Would you please elaborate.

  To me it seems like

Might be. Imho I find it a bit confusing, that ifupdown does not map its
events/PHASES to directories of the same name, i.e.
PHASE:pre-up -> if-pre-up.d
PHASE:post-up -> if-up.d
PHASE:pre-down -> if-down.d
PHASE:post-down -> if-post-down.d

I guess your point is, that NM's events should be changed to match the names of
the script directories, while I lean more to use the PHASE names

PHASE:pre-up -> NM pre-up event (not implemented)
PHASE:pre-down -> NM  pre-down (not implemented)
PHASE:post-up -> NM up
PHASE:post-down -> NM down

At the current state it is imho rather unlikely that upstream is changing his
position on this.

So, keeping status-quo means
- no support for pre-up/pre-down
- NM "up" event (correctly) mapped to post-up (scripts if-up.d)
- NM "down" event (incorrectly) mapped to pre-down (scripts if-down.d)

I'm a bit puzzled why you think that keeping down mapped to pre-down is
preferrable.
