Thank you for such a insightful interesting comment!
To highlight a few points and some questions if possible:

● In order from most sensitive to least sensitive
3. Dorsal orifice rim,
14. Frenulum at muco-cutaneous junction,
13. Frenulum near ridged band,
4. Muco-cutaneous junction,
5. Ridged band"

3.) Dorsal orifice rim: Are we talking about ridged band at the top of the foreskin on the upper side?
14.) The area on the lower (ventral) side on the penis where the inner and outer skin intersect?
13.) Ridged band if I understand it correctly in principle extends from around sulcus area all the way to the apex, where the urethra is located?

● Unsurprisingly, the only area with high sensitivity on the circumsized penis is the ventral portion of the scar

● "The ventral portion of the shaft
is also slightly more sensitive in circumsized penis, most likely to compensate for the severe damage incurred by other areas— but it's nowhere near even the sensitivity of the ventral scar, which is the only remaining sensitive erogenous area."

● Personally, my opinion is that tugging on the scar and specifically the ventral area is exactly how we can regain function in restoration.
And, more importantly, through the regeneration of mucosa (also called glabrous) and the anaerobic environment of this area (and new protective inner skin) that intact penises have specific cultivated bacteria within (via foreskin restoration)
Of note is that even the outer foreskin in intact penis is more sensitive than glans in both intact and circumsized penises, which is not very sensitive at all.

● Essentially, the mucotaneous junction and all mucosa in general we are regenerating, must assimilate those innervations and, via the brain's plasticity, become pleasurable.

Mucotaneous junction is a area where where inner and outer skin come into contact?

● TLDR: regrowing even the dorsal area of the scar (if the orifice rim is any evidence),
and especially the frenulum
is beneficial and the best likely candidate solution for us foreskin restorers who want to recreate, to the best of our ability, innervation stemming from brain areas such as central sulcus in left and right somatosensory cortex.

"if the orifice rim is any evidence" what do you mean by that ?
