Vue Conf Bonn follow up Question @evan

3.5 brought many custom element improvements. Will we get more features like access to the constructor for advanced features like form participation of CE.

3.5 brought a couple of new options for custom elements. Afaik it is still not possible to have access to the constructor or base class itself.
There are a couple newer features like allowing custom elements to participate in forms. This is done with attachInternals and the static formAssociated prop.

Svelte 5 added lower level control like this:

Documentation and ssr of ce is also kinda unclear at the moment. Is there any focus on improving ce support?
