I don't think f'{x.partition('-')[0]}' is any less readable as a result of the reused quotes,
Why are you reusing the single quote', which needs the escaping that you don't like, instead of any of at least 6 alternatives that do not need any escaping?
f'{x.partition("-")[0]}' f'{x.partition("""-""")[0]}' f"{x.partition('-')[0]}" f'''{x.partition('-')[0]}''' f"""{x.partition('-')[0]}""" f"""{x.partition('''-''')[0]}"""
It seems to me that that this is at least somewhat a strawman issue.
If you want to prohibit backslashed quote reuse in expressions, as in f'{x.partition(\'-\')[0]}', that is okay with me, as this is unnecessary* and arguably bad. The third alternative above is better. What breaks colorizers, and what I therefore object to, is the innovation of adding magical escaping of ' or " without \.
Or add a new style rule to PEP 8.
+1. It is even possible to add a SyntaxWarning in future.
