It is awful, privacy-wise, complicates the cache a lot and seriously
decreases hit rate in cache (since the key to a cached resource is no
longer type+name but type+name+source_address).

It is not just an issue of knowledge and skills. Even if you have
both, you may lack time, and prefer a shrink-wrapped solution. The
future is in "boxes" which are both ready-to-use (for the guy who
lacks sysadmin skills, and/or lacks time) and open (for the
tinkerer). The Turris Omnia <https://omnia.turris.cz/en/> is a very
good example.

With my TLD operator hat, I tend to say it is not a problem, we
already have a lot of extra capacity, to handle dDoS.

That would be a terrible violation of network neutrality. I hope that
such ISP will go bankrupt.
