It's awesome, I'm not criticizing Htmx at all to be clear, I am criticizing our seemingly inability to advance the core web technology of HTML in browsers to include this kind of tech natively.
If somebody from the WhatWG, e.g. Apple, Google, Microsoft, Opera, and Mozilla, etc. wants to embrace and support the creators of Htmx and wrap this into the browser natively, I will proudly retract my comment.
