I'm not sure what you mean by "it" in this case. Some of the things I use passive skills for were rolls back in the TSR days, some other things weren't. In any case, the paradigm in those editions were that DMs decided if something required a roll or not.It was always a roll up until passive perception came along in 5th (or was passive in 4th too, I cant remember now. There was take 10 and take 20 which were the precursors in 3rd, and were also a problem). Prior to that there was no such mechanic and stealth/perception worked just fine.
If you're talking specifically about stealth and hiding, back in the day there was no "perception" roll. People who wanted to hide had to narrate how they hid, and thieves rolled dice to beat a set target when Moving Silently and Hiding in Shadows. Characters trying to hide do the same thing now, only now the DC is set by their opponents' passive perceptions rather than a static number.
Passive perception was introduced in 4th, by the way. As was passive insight.
