Unfortunately the proposal to use f{ ... } for frozen sets cannot work within the constraints of Python's lexer:

Unfortunately we're running out of useful, easy to enter symbols for literals. Until such time (Python4000 perhaps, or more likely Python5000) as we can use a rich set of Unicode literals, I don't think there is any clear way to have a frozenset literal.

I'm not sure what the point is. frozensets are too rarely used to deserve a literal notation.
