But it makes sense, doesn't it? For example, if they were using Libre Office Base, M=1, F=2 would probably use the tinyint datatype. Since it can store values 1 - 256, it requires 8 bits. Using a boolean would save space since its only values are true, false, or null.
When they demand you change, use binary with F=0, M=1.
