Frankly the only valid usage cases relate to Unit Count and Credits. The other stuff is wanting to have excessive control over the interface.
I have a deathmatch mode in Star Strike, and being stuck to 15 units makes for a pretty short (but often very interesting) deathmatch. In RA1, selecting no bases increased the unit limit to 50 or something like that.
