Provide self-contained vue-router ESM production build

[roeltz]

What problem does this feature solve?

I'm trying to develop an application with a CDN approach to dependencies, and while the ESM production build for Vue itself works as expected without complications, VueRouter's ESM browser build is not a minfied resource and makes requests for many more dependencies (which also need an additional importmap entry for @vue/devtools-api). I've tried the global build vue-router.global.prod.js (even with some modifications on top), but the workarounds needed to make it work defeat the purpose of having an ESM-only architecture in the first place.

What does the proposed API look like?

For this, it would be ideal to have a proper production build, without any dependencies or instrumentation for DevTools (or have them inlined in the bundle), with a size comparable to that of vue-router.global.prod.js

Unfortunately, given the existing restrictions for importing other packages, this won't be doable. Instead, one has to rely on solutions like skypack
