It'd be a shame if the Tartakovsky Clone Wars stories were decanonized and jettisoned. There might well be some glaring discrepancies in continuity if one lined up the old episodes from a decade ago alongside the Cartoon Network/Netflix stories but there were characters and aspects of Tartakovsky's work that I remain fond of to this day. The bounty hunter Durge, for one, whom I believe would have made a fine addition to the roster of recurring villains in the Filoni series.
It's true that the old series doesn't feature Ahsoka nor other longstanding, familiar elements that helped make the more recent show so popular and highly regarded, but right now I imagine it's all up in the air along with much of the EU that's being scrutinized for inclusion in or exclusion from what will be the new, official, Disney-approved canon.
