I would say no and yes to your two questions.
Let me use an example to illustrate. If Langer's ball had been in a slightly more forgiving lie, the chip out would have been rather simple and the resulting pitch would, while being more exacting than a pitch on most courses due to the severity of #15 green, have been a relatively easy par. Similarly, if the trees hadn't been there, he would've been left with a difficult decision like Beck or Strange in the 80s: go for it with a very tough shot at eagle, or lay up. This year, and in the last few years, it's been a much clearer decision - very few people have attempted Vijay's daring shot.
It's obviously all a matter of degrees, but I don't think a poor tee shot should automatically mean zero chance at eagle. To me, that's penal design, not strategic. I'd rather see Seve eagle and double bogey from all over the yard than Langer methodically dissect a course. Both are great champions, so I suppose it's personal preference in many respects.
