I think this is right. If we consider Fuling to be minor fey, they kinda fall into the dwarf category of old norse mythos, as master smiths, hoarders, and power mongers.

If we bring the fantastic myth down to midgard, 'master smiths making weapons for the gods' becomes some magical technology that players can yoink from yagluth. So, the most likely is we get to make a new workbench using a Yagluth forehead or something.

As for dwarves hoarding riches and servants? It is possible, if improbable, that Valheim will add a piece of equipment (new belt or something?) that allows a variant of weight capacity or perhaps increases resources dropped.

Even less likely is the addition of NPC servants (Thralls). Let's entertain the idea: Yagluth thing becomes a command stone, that when added to a throne or some such, allows the player to summon a thrall to do their crafting. Plant/harvest crops, chop trees, defend base, travel with player, etc. Again, I think this is very unlikely albeit fun to imagine.

The last bit, dwarves as power mongers.. I don't have much speculation how this aspect could be added into game. So far, we have only seen damage (power) as a factor of equipment and skill, or powers as an ultimate ability from the stone circle. In the latter case, tick the box for Yagluth being a 'power monger' when we take their power.
