Hi,

There seems to be not much interest about this email, so I doubt that
the described functionality will be added to org any time soon.
However, let me try to give you some hints, which might be useful for
your personal config.

There is org-super-agenda package
(https://github.com/alphapapa/org-super-agenda), which already have a
part of the functionality. You can use :scheduled and :deadline
selectors as a starting point to achieve what you want.

A more direct way to approach this is a custom skip function. As a
starting point, see my own skip function for filter todo items with
deadline, but scheduled in future:

#+begin_src emacs-lisp
(defun org-agenda-skip-deadlines-before-schedule ()
  "Skip tasks, with deadline and scheduled in future and tasks without deadline."
  (require 'org-agenda)
  (org-with-wide-buffer
   (let* ((tmp-deadline-time (flet ((org-back-to-heading (&rest args) t)) ; we should be at heading already and it consumes too much cpu time otherwise
			       (org-get-deadline-time (point))))
	  (tmp-scheduled-time (org-get-scheduled-time (point)))
	  (tmp-cur-deadline (time-to-days tmp-deadline-time))
	  (tmp-cur-schedule (time-to-days tmp-scheduled-time))
	  (tmp-cur-day (time-to-days (apply #'encode-time
					    (append '(0 0 0)
						    (list (nth 1 org-agenda-current-date))
						    (list (nth 0 org-agenda-current-date))
						    (list (nth 2 org-agenda-current-date)))))))
     (when (or
	    (not tmp-deadline-time)
	    (and
	     tmp-scheduled-time
	     tmp-deadline-time
	     (> tmp-cur-schedule tmp-cur-day)
	     ;;(> tmp-cur-deadline tmp-cur-day)
	     ))
       (re-search-forward (org-get-limited-outline-regexp) nil 'noerror)
       (point)))))
#+end_src

What you want here is actually quite a complicated optimization problem,
which probably deserves a separate full project of its own.
I cannot comment much on this part since effort estimates never worked
for me.

Best,
