That would be desirable.  It would require a change to the
ifupdown package.

That idea seems a bit esoteric.  You could set this up manually
by putting a script in /etc/network/if-up.d/ which does something
like this (untested):

  #!/bin/sh
  [ "$DNS_DOMAINNAMES" ] || exit 0
  X="$DNS_DOMAINNAMES"
  N=$(host $X | grep -v 'not found' | sed 's/.*has address //')
  [ "$N" ] && echo "nameserver $N" | resolvconf -a 000${IFACE}-extra

The script should be named something later than 'resolvconf',
for obvious reasons.  Its if-down.d companion would be something
like:

  #!/bin/sh
  [ "$DNS_DOMAINNAMES" ] || exit 0
  resolvconf -d 000${IFACE}-extra
