If there are new ivars, we need to bump the library version, which is a pain
for packagers (upgrade GNUstep, upgrade all apps compiled against GNUstep), so
it's better if we can avoid this.
Is it possible to have a private subclass or something similar?

Yes, probably a good idea.
I'm not sure what we do with the library version for the non-fragile ABI. We
should only be incrementing it when we remove / change C symbols, not class
layouts, but I don't think -make has proper support for this yet.
