Why put the word "config" in the method name rather than just
``bool.from_str``?

Why not just check for the truth values?

    config = 'False'
    try:
        value = bool(float(config))
    except (TypeError, ValueError):
        value = config.casefold() == 'true'

I agree it's frustrating to have the 4 lines. Perhaps this is yet another
case that would be improved by exception-catching expressions (PEP 463)?

Unless those 4 lines occur very frequently, this feels like a bit too
special-case for a bool method. It feels more like it's part of a library
offering environment or config utilities.
