d20 (3.x) wasnt particularly adhoc about tons of things nor was PF... I bet there is more to it.
RAW, yes, in play my experience was that we ignored a lot of the rules that got in the way. d20 was held back by not being more ad hoc, which 5E has fixed, bringing the RAW and RAI closer into line with what I experienced on the ground. Once upon a time, I thought my group was weird, but apparently not.
