This is a problem. I wouldn't want to be in a position where we merge
this code in mainline, but it's just a not-very-useful toy. Then, as
we turn it into a useful non-toy it all turns into an utter mess.
IOW, merging this code as-is will commit us to merging more code which
hasn't even been written yet. It might even commit us to solving
thus-far-unknown problems which we don't know how to solve!
It's a big blank cheque.
So.
- how useful is this code as it stands in real-world usage?
- what additional work needs to be done to it? (important!)
- how far are we down the design and implementation path with that new
work? Are we yet at least in a position where we can say "yes, this
feature can be completed and no, it won't be a horrid mess"?
