I agree about perhaps offering more advanced artifacts upon the world but i disagree on this being a clear cut way to deliver them.
But from the way things are fleshing out, it seems like civs will be recieving world generation and 'lore specific' magical artifacts at start anyway to compensate, depending on the settings.
Over-diversifying strange dwarf moods to stretch thinly over other races wont achieve much i feel, and kind of ruin the uniqueness of dwarf culture, the world needs dwarves to create such ornate things or all that's left is mediocrity. Keeps dwarves in demand and relevance.
Though research i can get behind, since that is a field that is somewhat perfectly plausible since all civilisations churn out books and scholars and poets across the land travel to and fro. A book is a secret that is waiting to be learnt by a plucky adventurer is how i see it, as well as a chronicle of the person who wrote it's culture. Learn a little, perhaps how to make a orbitarium (or whatever that break-through object secret is that's triggered by astronomy research)
What amusement would be had to read a excavated and centuries old book, masterfully made and preserved by craftsmanship on the ornate manners to how to make steel, long forgotten by the remaining civilisations who since conquered and destroyed the dwarves and the material ends up in the hands of nobility only or slowly rusting away to worthlessness.
