I often wish they were _less_ configurable. Even Black's handful of config options are too many... Each one is a chance to pick a whole new color for the bikeshed.

That makes sense, but it's a problem when the formatter makes a rather opinionated choice and doesn't allow one to configure it. The primary example I'm thinking of in Elixir is comments for pipelines.

For example, if I use the pipe example on Elixir's landing page and add comments to it (obviously a contrived example):

    "Elixir"              # string to get frequencies for
    |> String.graphemes() # Get all graphemes (i.e., character units)
    |> Enum.frequencies() # Get the number of occurrences of each grapheme

This gets formatted by the Elixir formatter to:

    # string to get frequencies for
    "Elixir"
    # Get all graphemes (i.e., character units)
    |> String.graphemes()
    # Get the number of occurrences of each grapheme
    |> Enum.frequencies()

This is a rather strongly opinionated format stance, and as far as I know, it's not configurable.
