In Gecko, yes. The set of hooks Gecko builtin elements have today is,
effectively:
1) This element used to not have a parent and now does.
2) This element has an ancestor that used to not have a parent and now

3) This element used to have a a parent and now does not.
4) This element has an ancestor that used to have a parent and
now does not.
