Instead i believe that other attributes should be buffed in that regard. More checks of Agility to get in some places, more checks for Strength to move something out of the way or break it, more Int checks to figure how to get in somewhere or something like that.
Instead of lowering the threshold to find solutions to environmental obstacles, it could be neat to expand the solution set. For example, that Agility check really early on in the caves outside SGS, you know? Instead of needing 7 AGI(was it 8?) or else you fail, for that one, where the rocks are loose, a check against, say, 5AGI(or 6, whatever) plus 6DEX to see if your hands are dexterous enough to grab handholds, could also allow success.
Of course, that would just mean more work for the dev team, and the payoff might not be all that high. But there's a middle ground between keeping things as they are and removing the bar entirely. Still plenty of opportunities to fail a challenge, but expanding the solution set does increase the odds that a random player gets to see some stuff in a single playthrough. Those of us who've played it six, eight, ten times - well, we're way out on the edge of the distribution curve, so probably don't balance things for us
The expansion will probably expand the options for secret discovery, but a perceptive character will always be the most convenient option
Truthfully, I'd be surprised if Specialization: Snooping isn't a thing. We've already seen that specializations will modify our existing feats.
