I just tried it out with web components using Lit and it seems to work pretty well (https://i.imgur.com/PFvMgFp.png), allowing you to pass in on-page editable fields. But I'd be interested to hear where web components would work better than static/hydrated components.

Looks like that's using lit-html templates inside Svelte, but not any custom elements.

Web components would be good because they're an interface that Primo could work with without relying on specific implementation details. They're also encapsulated with shadow DOM, and support interoperable composition (components can have child elements made from any other frameworks or library).

So you could still build blocks with Svelte, but also Lit, Preact, Stencil, Vue, etc.

In a similar situation, I was advising the https://blockprotocol.org/ folk on how to define some interfaces on top of HTMLElement to allow standardized passing down of data to blocks, instead of requiring React in their case. I don't know how far they've gotten with that.
