Would it be possible to use AccessibilityObject::document() here, so you would not need to add AXObjectCache::document()?

Also, would it be possible to use AccessibilityObject::axObjectCache(), instead of having to add that new first parameter to AccessibilityObject::detach()?

I guess the answer is that it's probably too late here to get the document (and hence the AXObjectCache out of it) from the AccessibilityObject that is being detached, but I have to ask anyway :)

If that's the case, maybe it would be cleaner to swap the arguments in detach() and add a default value for the cache, so we have something like void detach(AccessibilityDetachmentType, AXObjectCache* axObjectCache = nullptr) that allows you to omit that "mysterious" nullptr parameter when not using ElementDestroyed as the "detachment type"

Correct

Yep. No problem
