A colleague implemented the PSL approach for Knot Resolver recently
where user picks the resolver set, but I'm skeptical about
spreading-with-PSL significantly improving privacy.  Still, it was less
than one screen of code (+PSL dependency) some people have asked for
this, so why not.

Trusting one provider seems better to me (or two... for a fallback).  If
you can't trust any, you probably need a Tor-like approach to separate
your address from your queries.

(For now I'm leaving non-DNS leaks aside, e.g. SNI, sets of IPs usually
determining the name uniquely, etc.  For now I'd go for a full VPN if
you trust a provider or Tor if you don't.)


Client-based splitting seems to be a worsening (!)  as one of privacy
benefits is precisely the inter-mingling of queries from multiple
clients and thus reduced ability to track the individuals.
