Questions that start "Should users really control" are anti-GNU/Emacs. (Only
half-kidding.) Users are not losers.

FYI, here is what the OP on help-gnu-emacs said, before his technical request:

IMO, users should be able to make windows dedicated.
And they are able to, AFAICT.

BTW, why do you specify "individual" windows here? Did you mean something
special by that? The OP wants to dedicate all windows for buffers in a certain
mode.

* To dedicate all windows, can't you just
  set `special-display-regexps' to include ".*"? 

* To dedicate all windows for buffers in a mode, can't you just
  add ".*" to `special-display-regexps' on the mode hook and
  make the var buffer-local? 

Those both seem to work OK. If you customize `emacs-lisp-mode-hook' to add this
function, doesn't it DTRT for you?

(lambda ()
  (make-local-variable 'special-display-regexps)
  (add-to-list 'special-display-regexps ".*"))
