Ah...but here you taint the question in order to get the answer you want.Lanefan, you've been enough of these conversations to know that this is just abjectly not true for 4e.
Lets you and I do an experiment.
Give me a good faith declaration in 4e D&D by (let's say) a Fighter of Paragon Tier and I'll tell you exactly how its resolved at the table. Assuming its good faith (eg not "I shoot an arrow to the moon") and not against the rules (trying to use a Ritual without the appropriate Trained Skill; Arcana, Nature, Religion),
Of course it is, because I'm limited to sticking within the rules.the answer is pretty much always going to be "yes" or "roll the dice (and here is what you roll)."
Without digging out and plowing through my 4e guides (which I ain't got time for right nowSo give me an example of a good faith action declaration by a Paragon Tier Fighter that you think the system can't handle, please.

Paragon Fighter - let's say no magic items other than simple +x weapons-armour-shield to keep things simple, and unbuffed by anything. Feats etc. are all focused on bending the foe's nose into its face, nothing esoteric here.

Our intrepid Fighter has no skill points in, say, picking locks. Picking locks isn't something a Fighter gets trained in as a part of her class. She needs to quietly get into (or out of!) a locked room, she has no key and bashing the door down is out of the question. What result comes if her player says "I try to pick the lock"?
In editions not numbered 3 or 4, the DM can (and probably must) rule on the spot for this: rulings-not-rules overtly stated in 5e and a similar unstated philosophy in 0-1-2. What I don't remember offhand is whether 4e has specific rules for unskilled attempts at things like this; but even hypothetically if it doesn't or didn't, then what?
Regardless, (and I'm rambling here a bit, sorry) the tipping point comes earlier: does the theme or 'feel' of the game and its presentation push the player toward thinking outside the box ("I'll try to pick the lock anyway, nothing to lose") or constrain her into thinking that because she has no skill or training she can't pick the lock - or worse, isn't allowed to even make the attempt.
Bah - sorry for the incoherence in this one.
