seems it's more complicated than that - if you remove all interfaces
from group carp, 'ifconfig carp' lists nothing:
$ ifconfig |grep ^carp
carp1: flags=8802<BROADCAST,SIMPLEX,MULTICAST> mtu 1500
carp2: flags=8802<BROADCAST,SIMPLEX,MULTICAST> mtu 1500
$ ifconfig carp
$
but with another type, this doesn't apply:
$ sudo ifconfig bge0 group em
$ ifconfig em | egrep '(0: |groups:)'
bge0: flags=28843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST,NOINET6> mtu 1500
groups: em
$ sudo ifconfig bge0 -group em
$ ifconfig em | egrep '(0: |groups:)'
em0: flags=8b43<UP,BROADCAST,RUNNING,PROMISC,ALLMULTI,SIMPLEX,MULTICAST> mtu
1500
groups: egress
