Is it possible to use just Quill deltas without Quill in ShareDB?

The documentation for the rich text type indicates that it is based on quilljs deltas.

However, the example in shareDB uses the Quill editor entirely, and I haven't found any examples online that don't.

I see that Quilljs is an editor with some quirks that I don't like:

• looks like a somewhat abandoned project.
• would add a lot of things to my project that I don't need or won't use
• I prefer not to depend on a library for my editor if possible.

I would like to know if I can create my custom editor with content-editable and connect ShareDB to it using only quill deltas instead of requiring the full quill editor. If possible, would you recommend doing it? Or will I find myself with a headache trying to solve difficulties that Quilljs has already solved?

On the other hand, if it is not possible to use rich-text type without QuillJs, then I wonder what is the advantage of using rich-text type, since from what I see when connecting quilljs to a WebSocket the RTC already works fine without needing ShareDB. Maybe I'm not understanding well.

Start with the rich-text documentation and the ShareDB Quill example, then compare the documented Delta interface with the integration points exposed to editors. A useful outcome would be a supported usage path or clear documentation explaining whether a custom contenteditable editor can use rich-text without Quill.
