Fair.This, more than anything, is why I hate when these discussions end up in binary poles. I hate the gameplay loop placing the generation of challenge in resolution creates. It feels miserable to play, it discouraged players from doing things unless they stop holding success as a goal, and it punishes them for doing the wanting I set above as their primary job. Players should be excited to deploy mechanics to defeat obstacles, they should delight in having the right spell prepared, bringing the right item, or spotting how their talent can be used to circumvent a problem means this thing they're engaging with is not a problem. It is equally problematic if the resolution system is undefined and the GM makes it up on the fly as it is if the system is designed to put them in a worse position by engaging.
I, personally, don't like the assumption of challenge/success-driven play outside of games in the OSR/NSR paradigms. For 5e, as an example, I don't think challenge play is the right paradigm; its ruleset and procedures push it in more of a performative/thespian play direction.
