eSNI can only effectively prevent people from distinguishing things which aren't otherwise distinguishable anyway. This is not a forgetfulness potion, if you already know by some other means where I'm going then eSNI doesn't fix that.

If cat-videos.example and elect-bob.example are just names for the same IP 10.20.30.40 then we can use eSNI to prevent eavesdroppers discovering which you visited and that's all.

But if you've got 10.20.30.40 assigned by your ISP for your personal web server then eSNI can't hide that, you can use eSNI to prevent eavesdroppers learning whether visitors were looking at snakes-control-nasa.example or soup-does-not-exist.example but if all you host are crazy conspiracy theory sites then they don't need to know which one is which to block all of them, that's just how IP works.

The configuration for eSNI is delivered over DNS, so it's up to you to choose how you want get secure DNS.
