Well that could be a bit misleading: while GNUstep policy has not accepted 
breaking the portability of existing code it has never prohibited the addition 
of new non-portable features (though obviously portable is preferred).

The granularity for enabling ARC is per compilation unit, which meant that it could be used for entirely new classes, but not for much else, and even then some of the private GNUstep headers are not ARC-safe (e.g. GSIMap.h) and so you'd end up with two completely segregated worlds within the same codebase.
