Consequently, what should take precedence are the expectations and

For them, having various features locally change the semantics of

Whoa.
Who ever proposed that? It seems a misunderstanding. No one is saying that,
e.g., destructuring formal parameters, or a rest parameter, should flip the
containing function into strict mode. Banning duplicate formals in no wise
does that.
We are discussing it for classes right now, and it has been on the
table for other features (such as arrows or generators) several times,
if my memory serves me right.
Two separate things:
1. All new syntax with code bodies makes strict-by-fiat code bodies.
2. New parameter forms restrict duplicate parameters.
Neither entails "various features locally chang[ing] the semantics of
unrelated constructs"-- unless by "local" you mean the new syntax's head
and "unrelated" the new syntax's body!
