I hope the following remarks are constructive to the subject.

They are constructive, but I disagree with the factual assessment:

It seems what's not liked about f{*x} notation is mainly that it looks parallel to f(*x) or e.g., often possibly f[(*x, )] ,

I think for many of us (specifically me, but I don't think I'm alone) it's equally important that we aren't persuaded that there's a need for a frozenset literal great enough to overcome the normal reluctance to add syntax. A number of important cases are already optimized to frozensets, and use cases and (more important) benchmarks showing that this optimization is important enough to add syntax so the programmer can hand-code it are mostly to entirely lacking.
