Oh, this is great news. I thought everyone involved with js (and coffescript) in rails were completely insane. Glad to see they were just doing the best they could in a crazy world (the early js world).

Wow that sounds great. It looks like it's still quite new, but I love having webpacker as optional in Rails 7 and just using ESM instead, which seems much more sane.

Still, there's the need to install NPM packages. You can use Skypack as a patch, but ideally you should be able to host all of your JavaScript. I guess you could use `npm` and manually link to those files in your configuration map, there could even be an automated Rake task to do it, but I don't know if that's the direction DHH has in mind.
