For monsters this isn't much of an issue (except when a player plays a monster). Its more important for NPCs. There it simply hurts immersion when the NPC can do thinks that the PCs never could or the other way around.
And for every stat you leave out you restrict the options the player have. For example what happens if the PCs manage to lure an NPC into a pit trap? Now it would be good to know what climb skill this NPC has. Without the rules for it it simply becomes an arbitrary DM decision which will mostly based on what the plot needs and not on the real capabilities of the NPC. For me this is a lesser form of railroading.
The point is that they aren't necessarily to include in the stat block. If you want NPCs to be built the same way PCs are, you just have to use the default 1/2 level + stat mod (+5 if trained). I don't see why these types of skills have to be specified in the stat block in order to use them.
Of course, in 4e there is no rule preventing you from statting out every NPC as if they were a PC. We've been told by the designers that this is an option, and that it will be no harder than it was in 3e.
Mainly what we are talking about here is a difference in GMing styles. IMC (even in 4e), I will stat out all of the important/recurring characters. It is the mooks, henchmen and other folks who will get the abbreviated treatment. For me, the demands of the plot/story/fun are more important than what may or may not have been written down on a sheet of paper as I was preparing the scenario.
What follows is personal, but not intended to be insulting in any way.
The issue I, and several other, posters have is that sometimes your posts come across as too authoritative. On many occcasions you refer to things other GMs do differently from you as 'railroading' or 'playing hack & slash' or 'playing a video game on paper.' There is no one right way to run or play an rpg. Making statements that imply that everyone else's style is inferior, can provoke a
reaction.
Since there is nothing stopping a GM from writing up extremely detailed character sheets for NPCs in 4e, the point
seems to be that those who don't want to should be forced to do so, or they are just hacking and slashing at their keyboards.
No monster in 3e has ranks in every skill. If a situation came up, the GM would have to adjudicate it, or pull a default number out of the core mechanics of the system. 4e would seem to be no different in this regard.
