Ever reused a UI component and spent hours guessing how it works? With Custom Elements Manifest, your components come with contracts: typed props, events, slots & CSS vars—great for docs, IDEs & storybooks.

Does anyone know someone from npm/github/microsoft?
We really would like to get a hold on the unused `owc` npm namespace - but we are not getting any replay since February 😅
We opened "npm Name Disputes submission #2569951"
any ideas/hints?

Look at that, @OpenWc just shipped some "spread" directives for @buildWithLit: github.com/open-wc/open-wc/b… There are A LOT of considerations to keep in mind when leveraging them: open-wc.org/docs/development… but, otherwise; glhf!

Version 2.1.1 of `@open-wc/scoped-elements` is out 🎉
With it, we no longer automatically load a polyfill for a scoped registry.
Which results in
⬇️ smaller size
👼 fewer errors when integrating components in pages
As long as you are not requiring scoping no change is needed

If you need scoping and you are already using `@open-wc/scoped-elements` then loading the polyfill for the scoped registry will enable it.
And if you are imperatively creating elements then you should use the `createScopedElement` method.
