Is there any relationship between current ifconfig on Linux and the
BSDs, other than the name? I don't think so. The BSDs have continued
to develop ifconfig, adding many features and options.

On Linux, you can do the same with ipv6
ifconfig eth0 inet6 add ipv6_address
but for ipv4 you have to label the NIC as an alias
ifconfig eth0:0 ipv4_address
You can use
ip a sh lo (if you have bash-completion installed, "a<tab>" will
complete to "addr" and "sh<tab>" will complete to "show")
instead of "ip a show dev lo" above (still longer than "ifc<tab> though).
