--- Comment #14 from Domenic Denicola <d@domenic.me> ---
We decided this capability was too low-level for custom elements, which now
have only (dis)connectedCallback which is about insertions/removals that change
an elements in-a-document status. A true inserted/removed hook would be run too
often and is not needed nearly as often.

It seems possible to add one in the future (maybe parentChangedCallback?), but
it's not clear the use cases are compelling enough. We have one request from
Hixie based on an analogy to SVG animations; have we heard authors asking for
this?
