Oh stop with that emasculated DM nonsense.
We've had a codified skill system in D&D since 1e with the Non-Weapon Proficiencies . Around 1985. Or was it '86? Go read the Dungeoneer's Survival Guide, The Wilderness Survival Guide, &/or Oriental Adventures. It was slightly clunky. It boiled down to; On a d20, with various modifiers, Roll Under your relevant stat.
Most played it that the lower you rolled the better the result.
So, assuming this optional system was being used at the table, DMs have been tasked with deciding what/how much info to give out based on a d20 roll for about 35 years.
Wich wasn't really much different than many were already doing it prior to these books & "official rules". Just now each class only had so many skills they could use & it was made slightly clunky.
And then pretty much this same system appears in 2e. This time it's right there in the PHB.
So once again, the DM has been tasked with determining what/how much info to give out on a dice roll.
The only thing 3e did was flip it from Roll Low to Roll High & introduce target DCs.
But somehow this time it was all removed from the DMs hands?? Pfft. Same job, different edition. Player rolls dice, tells you total. You decide how much to tell them. And if there's info you want to give them? Well.... You're the DM. You literally have the power (and the job!) to create the world, play everything in it that's not one of the PCs & can completely dictate what the PCs see/hear/smell/taste/feel(touch/& even know, etc. So you can just give it to them if you want. But if you really really really must set a DC? Because the rules say to? Just set it really low.
