It's unnecessary and inefficient to rebuild a config file that long every time you connect to a new wifi network,
well, you have used default and "default" server, where the "default" was not really default, because only configured domains were pointed to it. yes, you used undocumented feature of dnsmasq that gort removed. what you need is some kind of "server-alias", I guess you are welcome to provide a patch or hope someone will make it for you.
and btw this is also bad for your ssd.
have you never heard of tmpfs? alternatively, you can use multiple dnsmasq instances, one forwarding to default server and only named domains to the second instance. The second instance will forward to dhcp-provided nameserver(s).
