Aha, so the answer to my question

> Will switching on strict-order have the same effect

(in comment #42) is "No". So switching strict-order back on is no
solution. And solutions depending on strict-order including mine in #28
also won't work. Unless dnsmasq is somehow changed such that it
remembers the order in which nameserver addresses come in over D-Bus so
that strict-order is useful in the D-Bus case, if we want to avoid
breaking name service on machines connected to NNNs then we have to
disable dnsmasq by default; or disable it initially and only enable it
when we know that we aren't on a NNN.

(NNN = nonequivalent-nameserver network. As discussed in comment #5,
such networks are not properly configured. But as observed several
times, there are many NNNs out there. Which is why *many* people have
been commenting out "dns=dnsmasq".)

There is another problem with NM-dnsmasq (bug #1072899). Some VPNs have
multiple nameservers. NM uses dnsmasq to direct VPN domain name queries
to the *first* one. But then, if the first one goes down, the second one
is not tried. Once again, for the sake of speed enhancement in the
favorable case, users suffer radical name service failure in the
unfavorable case. This is not a good deal, IMHO. NM-dnsmasq should be
disabled by default until these problems are solved.
