Or to put it another way, if the only reason for the syntax proposal is performance then show me a case where performance is so critical that it warrants a language change.
It's the other way around.
The proposal (arguably) makes the code clearer but does not impact performance (and is a syntax error today, so does not break existing code).
The suggestions (decorators etc) make the code (arguably) clearer today without a syntax change, but impact performance.
So, those who think the decorators make for clearer code have to choose between source code clarity and performance.
