I believe that the current effort to make keyed archiving might cause massive
changes in the way .gorm's are loaded, particularly with internals of certain
classes as well as the custom class templates.
While, I believe our template system is similar, it is not the same as the one
on MOSX and it is, in some ways, better. We need to make certain that these
classes are minimally impacted by this change.
My intent when I suggested that we implement keyed archiving was to be able to
get XML output for .gorm files, whether that was MOSX compatible or not.
I beleive it is well worth the effort to try to make GNUstep and MOSX
compatible in this way, but I also believe that we shouldn't massively impact
current functionality to make it happen.
