Conversely, it gets easier to write outside tools that interact with Python code by removing corner cases and simplifying the grammar.

Yup, and that's terrible. It means people are likely to trip over it.

That sounds like a false economy to me. A one time small savings of developer effort (implementing the old grammar rule for decorators wasn't onerous?) to permit foolish and unnecessary intricacies among the laity.

Only if they are attempting to do something foolish. (Who puts whole expressions in a decorator!?)

Tell you what, you go find examples where people have tripped over it in the past and I'll code golf them to see if I can come up with something idiomatic and simpler. Does that sound like fun to you? ("Cause it does to me. Candy!)
