I don't think you are right here.
I dropped a script in /etc/network/*.d/ which dumps the environment variables
and activated an interface using ifup/ifdown
The relevant output is:

/etc/network/if-down.d/debug
PHASE=pre-down

/etc/network/if-post-down.d/debug
PHASE=post-down

/etc/network/if-pre-up.d/debug
PHASE=pre-up

/etc/network/if-up.d/debug
PHASE=post-up


You see, there is no down resp. up PHASE for the hooks in there.
Maybe you also understand, what I mean with that the names of the hook
directories do not reflect the PHASE variable.

I guess you misunderstood what I meant.
Changing the mapping in 01ifupdown from NM's down -> post-down
does not involve any modifications to ifupdown itself.
