Didn't read the entire thread because I'm at work. But all I've got to say is it's up the GM. If you want to make it harder, just do it and give your reason if the players ask why.
Well it's not the GM's game it's the groups game so if a majority see it as an issue then make the change, if not then leave it. This GM is a god paradigm is High School level thinking, time to grow up.
Well, that kind of thinking was also fairly incumbent to the d20 system and it's derivatives, with a lot of the game responsibility being placed on the GM's shoulders, such as being the final arbiter of the rules. It's only fairly recently that various game responsibilities are encouraged to be shared amongst the group rather than simply being left up to the GM.
Granted, there are gamer groups who've been doing this for a while and for whom such an idea of shared responsibility isn't anything new, but there are a generation of gamers who were introduced to this hobby and weaned on 3rd Edition D&D, where the only rules the players generally need to be aware of are the ones that directly impact their character, particularly what bonuses to apply and when to apply them (4e being fairly notorious for this).
And for some of these players, making the transition to a system where they have more of a shared responsibility in telling the story and interpreting the rules isn't a transition they are comfortable or even willing to make.
