I think its a good idea, the best idea even, but we still have no idea
what the requirements are without a clear case for an external index.
It could easily turn out that we invent a plausible API that's not
actually of use because of requirements for locking. Whoever wants
that can do the legwork.

IIRC each of the new index types has required some changes to the
generic APIs, which makes sense.
