@tmigone this should be in line with the discussions we had around this topic last time.
Legacy cuts should obey legacy logic (cut that the indexer takes), and are now all prefixed with legacy. Stuff that depended on that value should now use the legacy one for legacy code (i.e. on al non-horizon files), as well as the need for a full refactor of advanced metrics on legacy code, since there was also the effective cuts, and some advanced metrics that needed to be split into legacy vs horizon versions (otherwise they wouldn't have made sense)
