There were enough threads concerning displaying of buffers in Org, e.g.
https://list.orgmode.org/87mtnovv7f.fsf@alphapapa.net
https://list.orgmode.org/87zgrgke4b.fsf@ucl.ac.uk
Some users prefers multiple frames, others multiple windows in a 
full-screen frame. Could you, please, briefly describe what kind of 
behavior you are truing to achieve?

Overriding `display-buffer-alist' was certainly a mistake, users should 
be able to customize window creation. My impression is that 
`org-no-popups' is used in different scenarios that should have 
different default behavior.

Some Org buffers, in my opinion, should behave similarly to completion 
list. On the other hand `minibuffer-completion-help' does not use 
`display-buffer-overrining-action'. I do not like that this variable has 
higher priority than `display-buffer-alist'. Action argument of 
`display-buffer' is more appropriate since it keeps ability to customize 
placement of buffers with particular names through `display-buffer-alist'.

Thank you for suggesting `display-buffer-pop-up-window', current way of 
suppressing pop-up frames is unreliable. I am considering another 
option: '(nil (inhibit-switch-frame . t)) and I am unsure which variant 
is better. Actually I can not say that I really understand supposed ways 
to use `display-buffer' and related functions. My original expectation 
was that emacs should have a high level function for buffers similar to 
"*Completions*".
