Every time somebody mentions how awsome f-strings are makes me laugh. It was around ten years ago when Python community was looking down at Perl and shell with their string interpolation, but now that Python got pretty much the same it's suddenly not considered a misfeature.

We were wrong. We aknowledged it and improved. It's a good thing.

Have you considered that maybe the language had not evolved enough for them to be appealing. With b'' and u'' string syntax coming into the language, there is a realisation that string interpolation can be an opt-in feature among other reasons.

What you have is decision making analogous to the function

    evaluate(string_interpolation, python_ecosystem)

which is different from

    evaluate(string_interpolation)

This argument won't fly. Did you know that string interpolation in Perl and shell was always an opt-in feature? And despite that it was frowned upon by Python community.
