Why should it be so hard to tell find-dired to use a different window?

[Trevor Murphy]

I just noticed that `find-dired' and friends use 
`switch-to-buffer' as a subroutine.  Since this does not go 
through the `display-buffer' mechanism, it’s really hard for me to 
control where Emacs displays the Find buffer.  I’m currently 
advising `find-dired' to use `pop-to-buffer' instead.

I’m surprised that it works this way?  Does this bother anybody 
else?

Like, I could imagine an alternate world where that call to 
`switch-to-buffer' could be replaced with something as 
heavy-handed as …

   (pop-to-buffer (get-buffer-create "*Find*") 
   '(display-buffer-same-window (inhibit-same-window)))

… so that Emacs would still try very hard to display the Find 
buffer in the current window, but I could nevertheless override 
that by customizing `display-buffer-alist'.

Is there any particular reason to keep using switch-to-buffer 
here?
