There's a long list of worthwhile things for ahcpd...

It would be nice if openwrt's netifd play'd nice with ahcpd - an
example is with current openwrt syntax you can get a /60 prefix and
assign it automatically to /64 interfaces but not to ahcp managed
/128s

dnsmasq + ahcpd?

prefix distribution?

there's no way to get ahcp working across multiple physical
networks...

But I digress.
