That would hypothetically mean that for one smaller group of users
using Windows-style behavior every programmer has to be "strongly
warned".

Your explanation above is also not part of docstring and I do not say
it is necessary to be, but when you think there are such reasons than
maybe better is to solve how that understanding will arrive to
users. Understanding will arrive with good communication in the
docstring.

Instead of strongly warning against useful function it is better to
strongly make distinction in the description what that initial input
means as distinguished to the default value.
