Is this really worth the effort and the risk? This is clearly not ideal
when at a coffeeshop. And as a concept, unexplainable to endusers.

In my opinion, the way to do this is simply an option in Network Manager
that says "when on this network, trust and use the local DNS".

Simple. easy to explain to endusers. Easy to implement without python
modules. Does not change behaviour based on whether domains are DNSSEC
