Nor present in official specifications, in this case.

On <span> elements it is possible to simulate <br> elements. Internet Explorer
and Mozilla Firefox also simulate <wbr> the same way. Of course if other
browsers implement a UA stylesheet they will also implement this rendering.

See above.

> it's possible today to have a "br::after {...}" rule in your page
Chrome, IE (all modern versions), FF and Opera don't allow rendering for
br::after{}. Due to the "magic" of the element, probably, it doesn't allow
pseudo-elements, so I don't think anybody has used it, as it'd be useless.

> the use of 'content'/etc is actually rather slow and unoptimized
Is it possible to predict that {display-outside} is implemented more
efficiently? Only in that case this assumption is correct.
