I'm not sure how to do this well, and it's probably not worth too much effort (because probably nobody uses the Framework yet), but I guess we should be formal and clear about this?
"This" means how indexers will always return a DataFrame.
Maybe it's easy enough to maintain compatibility? After all, the IndexedPiece and AggregatedPieces models won't (at first!) be doing anything that requires a DataFrame.
