IronGate will add a proper ending to the last boss, when they get there. Right now, they are doing Milestone 2 of an early access game, focused on the Mistlands biome with the new boss. In other words, the last boss you defeated so far, wasn't the last boss. It was the last boss so far.

So whether you think IronGate should have made a proper ending or not, is a moot point, because it isn't the last boss of the v1.0 game. As of today, Valheim is at version 0.205.5.
