NO. where you see contrary ?!

Namespace DO NOT prevent you read/write that variable,
Just IF you know that var1 is in the stack1 namespace you need write
    
    stack1::var1

What problems?
I do not see any problems.

But now you get safe if TEAM developer several Rev stacks.
You are 100% safe that developers will not conflict.
Just NEVER. Just with ZERO efforts.

As for me, this feature can be EASY and logically be added into Rev
language.

Robert, it seems you think that NameSpace add scope.
And you cannot access vars in the scope.

Again no. Namespace DO NOT add scope.
This is where its beauty.
