(Caveat: I'm not following this thread.)

I don't use Emacs 28, with `repeat-mode'.  But surely
that should let you use its "machinery" conveniently,
no?  Wasn't that the idea behind adding it?

Anyway, this alternative is straightforward and works
fine, as a way to get a "self-repeating" command from
one that isn't.

(defun repeat-command (command)
  "Repeat COMMAND."
  (require 'repeat) ; Define its vars before we let-bind them.
  (let ((repeat-previous-repeated-command  command)
        (repeat-message-function           #'ignore)
        (last-repeatable-command           'repeat))
    (repeat nil)))

(defun next-buffer-repeat ()
  "Switch to the next buffer in the selected window.
You can repeat this by hitting the last key again..."
  (interactive)
  (require 'repeat)
  (repeat-command 'next-buffer))

(defun enlarge-window-repeat ()
  "Enlarge selected window vertically by one line.
You can repeat this by hitting the last key again..."
  (interactive)
  (require 'repeat)
  (repeat-command 'enlarge-window))

(defun isearch-yank-line-repeat ()
  "Yank buffer text till end of line onto search string.
You can repeat this by hitting the last key again..."
  (interactive)
  (repeat-command 'isearch-yank-line))

...


(You can also use `transient', but that's kinda
overkill for such simple behavior.)
