IIRC the current code is enough to run some things, but not to work to spec, and that's how it was discovered. I have the impression that it's being killed mostly because the necessary maintenance effort is unjustified. Some people talk about hygiene and killing old cruft, but AFAICT that's just an additional reason. It's not much code now, but the current state is untenable. It needs effort or removal.
