Lets address your points then
Exactly. Too simple. So it was changed for gameplay reasons. Like all other strangeness the game has you will not notice it once you get used to it.
I am not aware that 7D2D got dew collectors because Green Hell has them. At least this supposed reason you invented here is a lot better than the usual "TFP did it to prevent my playstyle"
Which choice exactly is prevented?
Like they are able to ignore the forge? You can find and buy water in the world and avoid dew catchers like you can ignore the forge and find or buy forged iron and steel and end products you would build in the forge. Exactly the same, right?
The thing is that the magazine system does not force normal players to do anything that they aren't doing already. Are you going through POIs collecting stuff? If yes, you will automatically find magazines. You don't need to change your routine at all if you don't flat out ignore the scavenging part
You know what would be real simple? Taking a jar down to a @%$#ing stream. That is simple.

Yes, Green Hell has dew catchers, that does not mean 7d2d needs to do it too. Even if you just "want to use this cool dew catcher model someone made", then by all means add it to the game, but it certainly doesn't make any sense to get rid of stone age concept of collecting river water to force players to use the new dew catcher, does it?

For one thing, Green Hell has dry seasons, 7d2d does not. And even in the dry season players could simply build near a source of water, and thus not need one.
It comes down to player choice.
The way this mechanic is proposed to function takes more player choice away from the game than it adds.

Honestly it is not even the addition dew catchers that @%$#es me off, it is removing the concept of "things that hold water" (i.e., jars) to force me to use a dew catcher that literally outputs jars of water that makes no @%$#ing sense whatsoever.
Players should at the very least be able to ignore that dew catchers exist if they do not want to use them, and have them as an option in a desert biome where they logically might some have a use for it.

Please stop railroading players with mechanics that should be at the very most, optional.
Which brings me to the skill system.
The current skill with experience points and collectible schematics strikes a reasonable balance, no need to waste dev time reinventing the wheel for this ridiculously convoluted magazine-based education system which forces people to waste time collecting McGuffins.
Players want to play in a sandbox, not a cattle chute
