FWIW, I randomly selected 100 commands among all 1285 (from gnus, org, and other packages I have loaded at the time) and tagged them. Among them 64 are  mode-specific commands. If my stat classes and wikipedia didn’t fail me, we have 95% confidence that the proportion of mode-specific commands is between 54.6% and 73.4%. (p = 0.64, n=100, using confidence interval of binomial distribution)

Command selection code:

(let ((command-list (seq-filter #'commandp obarray))
      elt sample)
  (dotimes (_ 100)
    (setq elt (seq-random-elt command-list))
    (setq command-list (remove elt command-list))
    (push elt sample))
  (dolist (x sample)
    (print x)))
