Not a fan of this, essentially the same as just having a hireling, but gated behind housing instead of a couple skill points. And tbh, I don't think they like the idea of hirelings/free mats and if they were starting the game now, I don't think we'd have the option for hirelings either, much like jewelry crafting.
The only two ways I see it going for adding it would either be its so weak its useless and just a glorified decoration that maybe gives you a couple things here and there, or OP and market effecting.
