No.Rules light is a pretty subjective term. I think there are roughly : heavy, medium, light and minimalist RPGs. I would say 1-2 page RPGs is more on minimalist side. If we are just talking core rules, not rest of book (spells, monsters, etc), I think like 2-8 pages rules is rules light. But page count alone doesn’t really capture it.
For D&D early versions of basic strike me as rules light (not rules streamlined but rules light). AD&D I would say is not rules light, but certainly lighter than most of the post TSR editions
Rules light is neither good or bad IMO. I personally tend to fluctuate between rules light and rules medium
Simulation is a weird term. I don’t use it myself. Can’t stand the term but often find my style gets labeled that for whatever reason. It seems in past couple of years some gamers have actively embraced the label (but I think they use it differently than I would)
Early versions of D&D are rules absent. That's not rules light. When you have no rules for covering basic actions that a game could reasonably be expected to see, that's not rules light. So, can you character swim wasn't answered in older versions of D&D. That's not rules light. That just pushes the rules over to the DM who then decides on an ad hoc basis what rule that table will use from that point onward, thus increasing the rules load. In a rules light game, like, say, Savage Worlds, you have one rule - can you beat a 4? The DM (and possibly the rules) picks a die size for you to use depending on difficulty and you make your roll. Doesn't matter what you're trying - swimming or flying an airplane. One rule.
That's rules light.
The problem is, you're simply comparing versions of D&D and saying, "well, this version of D&D has less rules that that version, so it must be rules light". That's not what it means. Having less rules doesn't necessarily make a game rules light.
But, that's where it gets into all the edition warring nonsense and shenanigans. People simply massage the definition into something that gives them the results they want, and then they proclaim that to be a fact. Rules light is not subjective. It's defined by its center, not by its edges. But, people will simply play ridiculous semantic games in order to promote their personal favorite edition.
