I guess this also means there's a change in behavior here?

I don't think so because "allow declarative shadow roots" is only false for inert documents created for the purpose of fragment-parsing, and those are never cloned AFAICT.
In blink "allow declarative shadow roots" is a fragment parser config rather than something that stays on the document.

What about XMLHttpRequest? It's not setting that flag today and I think that was intentional. Do we have tests?

https://whatpr.org/html/12624/parsing.html#allow-declarative-shadow-roots is false by default, and https://xhr.spec.whatwg.org/#document-response uses the default settings, so I think spec-wise this is OK.
There is a test for this here.
