The only gimmicks needed are bc and no load times.
My man.
You can go back even earlier than the Sixaxis for a Sony debut controller technology that fell on its face. They made every button on the Dual Shock 2 analog and then had to tell developers before the console even came out to take this functionality out of their games because it would wear the controllers out in a few months.
IIRC, they wouldn't even give a pass to Gran Turismo since they suspected, rather accurately I imagine, that enough players would play just that for long periods and do it.
I don't recall reading anything about whether they had ever fixed this or if later versions of the controller just quietly dropped it. Also no idea if you can detect it if they did.
PS2 didn't drop it. The controllers were needed to be analog just to play MGS2 (the only game that uses them besides GT, IIRC). Same reason it was on the DS3/PS3.
PS4 dropped it because at that point they dropped BC so there was no need to continue to have a feature that nobody was really using.
(Fun fact: X-box also had it. Dead or Alive: X-treme Beach Volleyball had the option to 2-button [analog] or 4-button [digital] control scheme. It's the only game to use them, IIRC, on the X-box. ...Oh no, wait, MGS2 was ported to X-box as well so I think it uses it, but the PC port didn't.)
