I mean, yes. The 3E-style Sorcerer should have been deleted in 5E.
The problem is, the Sorcerer in the DND Next playtest was a cool weird spellblade-kinda class that justified it's own existence. And after the last Next playtest, WotC just bait-and-switched it for the 3E Sorcerer, with no warning and despite them saying it was popular (and not testing if the 3E Sorcerer was - I strongly suspect it would not have been). So it essentially just got slipped in as part of Operation Apology Edition, which also used time-travel to airlift the Monk directly from the 1970s to now, for no good reason.
Now they're trying to give Sorcerer some kind of identity as a sort of "magic barbarian" in that it has a Rage-like ability and stuff, but it's still essentially overlapped pretty hard by Warlock and Wizard.
