There is a third option that you should think about: You could implement 
the missing methods and donate them back to the GNUstep project. 
Contributions like this are highly welcome and if it involves simple 
methods like the ones listed above you could get away without signing 
all the copyright assignments, although that isn't much hassle. It just 
takes some time :-)
