Per-domain DNS servers can't be configured globally via files in
resolved, only per network device. However, you said in the bug that
this isn't working on the host anyway, only from within containers.
And for those lxc sets up its own dnsmasq which the containers use
as DNS server, so nothing should change in that regard, unless you are
planning to replace lxc's dnsmasq as well.

FYI, this can be made to work on the host if lxc/lxd would register
containers in machined, then libnss-mymachines will resolve those
