I should have said "special-display".

I don't; I never said I did. I was describing my overall use, including my
use of `pop-up-frames', not my use of *Help*. You expressed some assumptions
about users with non-nil `pop-up-frames' and their never reusing a window
and never splitting a window. I was explaining that although I have
`pop-up-frames' non-nil, I still sometimes reuse or split some windows (not
*Help*, but others).

And I explained that I don't personally need you to delete the frame - I do
that myself. Deleting the window is sufficient (for *Help* or any other
buffer).

I don't know or care what the default value is.
FWIW, I have that set to `t'.

No I won't. In that case, you can show again the non-view-mode buffer that
inhabited the window before the view-mode buffer that was quit.
If there was a buffer in the window before the view-mode buffer is placed in
it, then it's OK to show that buffer after quitting the view-mode buffer. If
there was no other buffer in the window before the view-mode buffer, then
there is no reason to display any buffer at all there - just delete the
window. And if the view-mode buffer is `one-window-p', then delete the frame
also.

I understand. Don't worry about the frame-killing part, at least for me. My
own code does that.
I personally think that the test of `one-window-p' should be sufficient for
deciding whether `delete-window' should also delete the frame, but I think
that some others might disagree with that. For my own needs, it is enough
that Emacs delete the window - my own code will then DTRT (for me) wrt the
frame.

Then I already provided my feedback, IIRC.
Thanks for working on this, BTW. I realize that it is not so easy to juggle
the many possibilities, including different use patterns.
