Bring back hgroup

[grayghostvisuals]

Not sure how much I need to give a case for this but many developers out there saw the hgroup as something worth keeping.

<hgroup>
    <h1>Title</h1>
    <h2>subtitle</h2>
</hgroup>

hgroup is alive and well! https://html.spec.whatwg.org/multipage/semantics.html#the-hgroup-element

It's true that some other standards orgs, which are unable to write their own specs, have forked the HTML Standard and made their own version with different rules. But those are not interesting or anything you should pay attention to; anyone can fork, but there's only one HTML Standard.
