I want sortable tables without having to rely on a third-party plugin to a third-party library. HTML describes content, not just layout. It would be a `sortable` attribute on the table, just like you already have attributes that have nothing to do with layout such as `autocomplete` or `aria-*`.
It's all fine and dandy until marketing bros decide to shove all kinds of shady modals into that JS file. The JS side is not exclusive to trivial interactivity.
It's open source software. You can see what it does, and you just put it on your server. We're talking about pre NPM javascript here, no continuous deployment, everything is vendored and local and no one is going to change that file without your knowledge and permission. And if someone does, you have much bigger problems on your hands.
What you can't own and control is the browser vendors and how they choose to implement things, or not to. You can edit a JS file to your specific needs, but you're stuck with whatever the browser decides.
There is an incentive to use HTML for common interactivity purposes.
