Exactly, these and several other compatibility options [0] are a long
known (well I thought so) deficiency of inetutils ifconfig, that's why
at least in Debian and derivatives it's installed as inetutils-ifconfig,
to avoid breakage. The OP did not seem to be using a packaged version
of inetutils though.

[0] At least for the net-tools backend the up/down, add/del, tunnel,
hw, multicast, promisc, dynamic, tailers, arp, outfill, allmulti and
keepalive options are not implemented. It does not support specifying
the address family (as in “IFACE [[AF] [ADDR]]”). It does not support
IPv6. By default only prints the loopback interface, instead of all
active ones. The missing -a option to list all interfaces regardles
of their active state conflicts with the native -a address option.
Some information is missing when printing, namely the metric, the
collisions, and the transfer stats (in packets and bytes).

For the other system backends there's some comments on what might be
missing in system_parse_opt_rest().

Yes, they surely do.
