I concur with my 2c.

This seems more like a job for a custom local DNS proxy than
it does the resolver code.  Then it would also work for any
application that used /etc/resolv.conf but not the resolver
routines from libc.

Either way, I doubt that I'd use the proposed feature: unless
my ISP starts redirecting DNS traffic away from its true
destinations to their own servers I won't care what their
severs do. Since dialup days I've always run a local caching

I've not measured recently (and it was probably three ISPs
ago) but a local caching server used to be both faster and
more reliable because it avioded the ISP's DNS server(s) as
a point of failure.  Since then it ain't broke and I ain't
fixed it. :-)
