systemd should be listening on this socket

Well, on no less than four different Debian machines, it does not.

$ sudo lsof /run/systemd/userdb/io.systemd.DynamicUser
COMMAND PID USER   FD   TYPE             DEVICE SIZE/OFF NODE NAME
systemd   1 root   28u  unix 0x0000000073ac41e2      0t0 8696
/run/systemd/userdb/io.systemd.DynamicUser type=STREAM (LISTEN)

Isn't that on a machine where systemd-userdb is installed maybe? The
installation of that package triggers the systemd binary to listen?

No, systemd-userdb is not installed and as you can see from the above output it's actually systemd which listens on that socket.
