The ability to read config fragments from a directory has been in
dnsmasq since version 2.32 (effectively, forever). The Debian (and by
inheritance, Ubuntu) packages have created and automatically searched
/etc/dnsmasq.d since 2.46, released in November 2008. That's not quite
old enough to be in the current Debian stable, which has 2.45.

All this is slighly moot, since this scheme needs changes to dnsmasq.
Those can easily go into the next release.

Almost certainly. Could this be a hook supplied by the distro packaging?
