Hi Simon.
Before I forget to ask: can you please update dnsmasq(8) to include
under "--strict-order" a description of what happens when nameserver
addresses are passed in via D-Bus instead of via a file?
You wrote,

Because NM doesn't use dnsmasq to cache, if NM were to give dnsmasq only
one address then I guess the only service that dnsmasq would still
provide is that of name-to-server mapping.
And it turns out that the way NM currently uses dnsmasq to do this is
seriously flawed. So I conclude that it's better for NM not to use
dnsmasq at all until these problems are solved.

confirm (1) that it's possible to give multiple server options as
follows
server=/google.com/1.2.3.4
server=/google.com/5.6.7.8
and that the result will be that 1.2.3.4 and 5.6.7.8 will be treated
equally for the purpose of resolving names in domain google.com? (2) And
likewise via D-Bus?
(3) What effect does strict-order have on this?

What you say here suggests that my proposition #1 above is false. If #1
is false then it seems that in order to fix
