I thought Jorge wanted something that works with existing (and elder)
Emacsen.

We could easily do that but for one issue: Some buffer display calls
expect that neither snow nor rain will prevent Emacs from producing a
suitable window (compare bug#15213).

Also, a user's expectation that code following

  (pop-to-buffer (generate-new-buffer " *temp*"))

operates on the new buffer is not entirely silly given our current
understanding of `pop-to-buffer'.  Many years ago I asked here whether
anything might prevent the display of a buffer but no-one had the
courage to answer ...
