Well, let me ask you this two parter, in relation to your thoughts.
1. What exactly is the Right'(tm) thing?
Doing what the game teaches you.
Staying out of range.
Sneaking. Keeping the stealthbar low.
Not making noise (papers, hitting stuff, looting)
Usign silent weapons.
2. Are you actually being punished?
If the only way to clear a POI is taken away from me because I chose to skill in stealth instead of guns? Yes.
Stealth doesn't need to work perfectly. There are too many factors to take into consideration when determining the outcome, and those too are also 'mechanics', and just because you felt like you were just performing the play style doesn't mean you get to evade all negative outcomes. That's not only unrealistic, but also would make the game just plain boring if 7Days turned into a zombie sniping simulator. There are app games for your phone if you want that sort of thing.
But this isn't a war simulator. Simple mechanics work best. If games with AI were to try and emulate "realistic" behaviour, nobody would play them.
Imagine if in splinter cell enemies would randomly turn around. You would need to quicksave so often, it would ruin the game.
Stealth needs to be predictable, or its not fun.

Yes they actually want you to fight. But they do not give you the tools to do so.
I can't fight hordes of zombies with a bow (especially lategame).
There is no gameplay reason otehr than "we want to player to engage with zombies" for unpredictable wake-up!
And that is a valid reason. But they don't give you any tools to do so.
That is the huge drawback of this "attribute-skillsystem".
You can only do one at a time (at least efficiently), so if you perk into something, you are good at that thing, nothing else.
You have to chose if you want to eat... oh well this is off topic.
Point is:
Sure you can use an AK without any perks in it.
But if you can survive without perks, perks are useless. If you need perks, then you are f***ed if you go into stealth.
Either way it is a fundamentally broken system right now.
You can have fun. 100%. It is a great game. But these systems work against each other, not with one another.
PS: My only point is this:
If the player is skilled enough, he should theoreticially avoid everything.
Make it hard. Make it so hard that it is nearly impossible to do.
But a good player needs to be able to "avoid" more that a bad one.
But right now, normal stealth is so easy, you can sneak right next to zombies without worry... and auto-wakeup have nothing to do with skill... so low skill and high skill have more or less the same outcome.
and even with the best diplomacy you might fail a quest.
Then the game is broken and needs to be fixed.
IF you do everything right and a random roll still f***s you over, the game punishes the player, not the character.
Name me one RPG where with ideal play you can still fail. Obviously there might be some... but none that I ever played and I played A LOT!!!
And if that game makes you fail, is it reasonable?
Like did you kill the kings daughter?
Or is it "meh we just want to to fight lol! What? You put all your points in diplomacy and can'T fight? Well too bad haha!"
