If you think about it, if an individual is capable of performing "heavy" squats (how are we defining heavy, over 60-70% of 1RM?) and they are an intermediate to advanced lifter with good form, then it's pretty much a given they will have good core.
I still think you shouldn't ignore core stability exercises, especially after a lay off from weights and before a program of S&T.
This, as always, depends on the individual though. Something which is inherently fundamental to the prescription of all training and which unfortunately appears to get forgotten by people seeking to understand training principles for the first time.
