Well yes, except that ideally one would be able to run these things,
and even have them provide nameservers, without e.g. having them
clobber the domain search list.

(Not to criticize your code - I have no idea what your code does, but
some of the programs that historically scribble in resolv.conf do
rearrange things rather freely.)

No, you have an include directive in /etc/resolv.conf at the point you
want. Or you don't have it at all, if that's what you want. Simple and
easy to manage.

I don't see how this is relevant to management of which state is kept
where...
