Let me come back to this, because I think it is not quite working as
intended yet.

The goal is that the "right" resolver is chosen via alternative
priorities, right? So during build time, we set /etc/resolv.conf to what
is the desired resolver.

However, there's still a L+ entry for /etc/resolv.conf
in /usr/lib/tmpfiles.d/connman_resolvconf.conf:

L+	/etc/resolv.conf	- - - -	/var/run/connman/resolv.conf

As a result, when systemd is used and the rootfs is read/write, then
systemd overwrites /etc/resolv.conf, leading to:

# ls -l /etc/resolv.conf 
lrwxrwxrwx    1 root     root            28 Jul  6 14:44 /etc/resolv.conf -> /var/run/connman/resolv.conf

That happens even if systemd-resolved has a higher priority and should
be used.

Maxin, do you agree? Can you finish this work and patch the ConnMan
recipe so that it behaves as expected?
