No, there isn't. ::outside will only exist if given an explicit 'display'
value. But assuming you had:

   td::outside { display: inline; }

Yes. Why is this a problem? It's just the same as if you were adding an
actual element. Why does this require this "to [be] carefully considered
if not outright banned"?

Yes, I agree this should be mentioned, if it isn't already.

You could also side-step it just with:

   td::outside { display: table-cell; }

...without changing the inner <td> element's display. Since it is the only
"child" of the ::outside pseudo-element, it will just have its own table.
