I think it makes sense to add new functions incrementally, as long
as we try to only extend the API in a way, so that it is compatible

payload patch is committed we can work on a more sophisticated per-
doc-metadata solution. Until then we can use payloads for that use
case.
I respectfully disagree with this plan.
APIs are forever, implementations are ephemeral.
By making a public API available for one aspect of the flexible
indexing format, we limit our ability to change our minds about how
that API should look later when we discover a more harmonious solution.
If we're going to go the incremental route, IMO any API should be
marked as experimental, or better, made private so that we can toy
with it "in-house" on Lucene's innards, auditioning the changes
before finalizing the API.
