I arrived at the wrong conclusion as Matthias points out.
>>> import ast
>>> ast.dump(compile("f'{x=}'","<string>","exec",ast.PyCF_ONLY_AST))
"Module(body=[Expr(value=JoinedStr(values=[FormattedValue(value=Name(id='x',
ctx=Load()), conversion=114, format_spec=None, expr_text='x=')]))],
type_ignores=[])"
>>> ast.dump(compile("f'{x!r}'","<string>","exec",ast.PyCF_ONLY_AST))
"Module(body=[Expr(value=JoinedStr(values=[FormattedValue(value=Name(id='x',
ctx=Load()), conversion=114, format_spec=None, expr_text=None)]))],
type_ignores=[])"
if expr_text is removed those strings will be the same, so we will be ok. Sorry
for the confusion.
