> What was determined is is not economically viable which even SpaceX has started to realize on some launches where they ditch the landing in order to be able to carry more payload. SpaceX hasn't "started to realize" that, they always knew that some F9 launches would be fully expendable and they've been occasionally expending F9 boosters from the start. Not because there's something wrong with the economics of booster reuse generally, but because expending a booster is sometimes (not usually) worth it to get more mass into orbit (roughly double to GTO with Falcon Heavy if they expend the core stage.) That extra performance was always known to be required for some payloads, but isn't required for most payloads.
