No, cultural items would have to be decided on a case-by-case basis. What if one culture thinks hauling a large rock on their back continuously is a requirement for the good will of their gods? Should Starfleet allow an officer to constantly haul a boulder around just to be fair? If it interferes with their work, it can't be allowed. Worf's baldric, Ro's earring, and Nog's head dress were all approved, but that doesn't mean that all adornments must be included across the board.
Starfleet doesn't have to be "fair".
The boulder is a ridiculous comparison. Nog's headgear and Ro's earring are both items that can be worn and don't interfere with their work. Earrings and boulders are apples and oranges.
