+1 !

I think we should focus on everything that's *infrastructure* in 4.0, so
that we can develop additional features in subsequent 4.x releases. If we
end up releasing 4.0 just to discover many things will need to wait to 5.0,
it'll be a big loss.

So Codecs seem like *infra* to me, and can we make sure the necessary API is
in place for RT Search and stuff? I think a lot of the new API in 4.0 is
@lucene.experimental anyway?

In short, if we have enough API support in 4.0 already, we can release it
and develop features in 4.x releases. The only thing we should 'push' is
stuff that requires API serious changes (I doubt there are many like that,
maybe just Codecs support for the stuff you mentioned).
