I can agree with that. It had other effects too, like it offered opportunities for the lower nobility to gain prestige and connections, or it added a unique cultural color to the court.
Most stuff prior are establishing relation with the Árpáds, the OG Hungarian dynasty, the marriage relation to them and the claim of ancestry that came with it gave the Habsburgs legitimacy. Some of em put emphasis on this, some not at all (such as Joseph, son of Maria Theresa).
