I stand corrected for what I wrote ; you explained better than what was my original thought process, which from hindsight was missing a few steps in transition to what I actually meant to say. Nevertheless, I concede to your point.
Kuznetsov did have old black and white photos showing her with med mooring, but that maybe for another time.
The dimple in the buttcheek was where the big shore round fender/s would sit and two gangways in the back were used for people exiting in and out.
See the picture herein at dry dock. They put a longer bigger gangway to access and exit from that back entrance , instead of using existing shorter skinnier ones tucked in behind. Soviet wouldn't put those in place if they didn't intend to use, which is especially handy when you do the med mooring. China does not need to go that route as whole berthing infrastructure was built for each AC to moor alongside. Hence the word vestige. But anyway, I digress.
