Is this also true for Windows and other platforms?

And I don't think it's about whether or not people are likely to
specify sizes in gigabytes on old machines. People are bound to
blindly copy configuration files from one machine to another. In
any case, my expectation would be for the configuration options to
do what I tell them, or error out if they do not make sense.
