There are actually multiple paths already! In addition to NextDNS, there is:

HNS.to (No DNS configuration or downloading needed), LinkFrame (Chrome extension), Resolvr (Firefox add-on)

Here are some use cases! https://learn.namebase.io/starting-from-zero/how-to-use-hand...

Sure I can use it for some things, but no one else can. I can't even get an SSL cert for them, or control DNS using an API like I can with Cloudflare (I can setup my own BIND server, but its a lot more work for not much gain).

I can use a gateway like HNS.to to share it with other folks, but thats uglier than a normal domain and bad practice due to shared cookies and the like.

Its just not worth it right now.
