The spec doesn't say what should happen to shadow DOM
if host is adopted to a new document.

The spec does have "The ownerDocument property of a node in a shadow tree must refers to the document of the shadow host which hosts the shadow tree."
but that misses 'adopting steps' from DOM spec which HTML relies on.

@annevk , I think this issue now should be addressed by DOM Standard directly.

@hayatoito does it match your understand that in https://dom.spec.whatwg.org/#concept-node-adopt I would change "inclusive descendant" to https://dom.spec.whatwg.org/#concept-shadow-root-including-inclusive-descendant. That way all the associated shadow trees would be adopted too. I'm assuming that's what's implemented.

Perfect. That would match my understanding and the implementation. Thank you.
