Possible solution:

I have suggested over the years—as have probably dozens of other people (maybe thousands)—that that would be a great spelling if Python were a brand new language.  But in reality, Python is 30+ years old, and billions of lines of code use `{}` as an empty dict.

Historically, Python had dictionaries before it had sets, so there was more than a decade in there where sets were not a thing you could spell at all.  A breaking change isn't something that's going to happen here.
