Good, let's not do it then.  In any case, just for fun and because it
could be useful in some other situation, I proposed in bug#62068 the
suitable additions to map.el.  Then the conversion we were discussing
looks like this:

(defun dotted-to-nested (items)
  (seq-reduce
   (pcase-lambda (map `(,ks . ,v))
     (map-insert-in map
                    (mapcar 'intern (string-split ks "\\."))
                    v
                    'plist))
   (map-pairs items)
   nil))

(dotted-to-nested '("a.b.c" 1
                    "a.b.d" 2
                    "a.e.f" 3))
=> (a (e (f 3) b (d 2 c 1)))     [modulo bug#62067]
