I love this- I'll give it a spin. I'd really want web developers to start making websites again that can run without javascript, but it can feel like a SPA if JS is available. This has always been 'possible' but, in practice, it's a massive pain. uJS and HtmX could help to be the polyfill solution to make this possible.

That said, I worry about Form elements being controlled by uJS to use a different REST method (like DELETE), and this would cause JS-free browsers to break.

Glad it clicks! On the progressive enhancement point, µJS is designed exactly with that philosophy in mind: standard links and forms work without JS, µJS just enhances them.

Your concern about `mu-method="delete"` is valid. Without JS, the browser will fall back to the form's native method (usually GET or POST). The classic solution is the `_method` hidden field pattern: the form submits POST with a `_method=DELETE` field, and the server reads that field to route the request correctly. µJS doesn't need to implement anything special for this, it's a server-side convention
