I talked about both issues with Michal Sekletar, which is systemd and
avahi maintainer for RHEL and the situation is following:

1) systemd-resolved as successor of nss-mdns module:

    As far as Michal knows, systemd-resolved is not currently meant as
successor of nss-mdns module + avahi since it does not support service
browsing as Mike found out. If it will in the future, he does not know
right now (probably how avahi situation will turn up...).

2) Avahi upstream maintenance

   Michal and several other people tried to convince Trent to pass
ownership to someone else (Michal knew about two people, who would like
to take Avahi project at that time) about two years ago, because Trent
seemed to do not have time for the project. But Trent did not want to
give away the upstream project. Currently Michal fixes Avahi issues
downstream in Fedora/RHEL.

Is there a way how to solve the situation? Cloning the project is not
optimal, because Trent's github repo is still the first obvious choice
when you google 'avahi github'.
