Makes sense. I've always assumed that OpenBSD has a very narrow use case anyway. I love it for a network firewall because the configuration files are sane and easy to understand (stares at systemd networkd). I set it and forget it.
it is easier to setup a openbsd vm and have it handle all the network routing and wireguard stuff, than it is to simply disable the unrequested zeroconf stuff included in systemd-networkd/resolvd.
I personally think systemd, which I despise, won and effort would be better allocated trying to improve it (e.g. ripping the zero conf stuff from it to begin with)
