I’m on version 12 and it still seems completely random. I use QKSMS and it persistently tried to put my boss and extended family’s SMS quicklinks at the top of the sharing menu, so I had to download a program called Watt and disable QKSMS’s sharing module manually to stop it from happening. If it could just deterministically let me enable/disable and/or sort the sharing menu I wouldn’t have to live in fear of it.
