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.
