Given mDNS implementation in systemd, I was expecting Avahi to be long dead and systemd to hijack Avahi's DBUS interface.

That didn't happen?

Maybe systemd still lacks ability to publish static services? My /etc/avahi/services contains couple of files, last touched twenty years ago.

systemd-resolved does not, in fact, lack the ability to publish static services (systemd.dnssd(5) tells us how), but it does lack the ability to publish dynamic services (or compatibility with Avahi's D-Bus interface in general), which is why we can't get rid of Avahi altogether (highly unfortunately).

Oh, I was wrong here.

$ busctl --system introspect org.freedesktop.resolve1 /org/freedesktop/resolve1 org.freedesktop.resolve1.Manager

But, no compatibility with the (much more extensive) Avahi D-Bus interface—or any of Avahi's alternative APIs which are wrappers over the above.
