this conflicts with pylint C0209

Formatting a regular string which could be a f-string Used when we detect a string that is being formatted with format() or % which could potentially be a f-string. The use of f-strings is preferred. Requires Python 3.6 and py-version >= 3.6.

I usually disable this one. It makes sense for codebases that support Pythons below 3.6 but not for us.
