> Today its only usable really by stored fields/term vectors, has hardcoded logic in SegmentMerger
specific to certain impls, etc.
> It would be better if this was generalized to terms/postings/norms/docvalues as well.
> Bulk merge is boring, the real idea is to allow codecs to do more: e.g. with this patch
they could do streaming checksum validation, or prevent the loading of "latent" norms, or
other things we cannot do today.
