Should work page be under the arranger or under anonymous?

[Charanguero]

I want to add a new arrangement and recording of Arirang, a traditional Korean melody by an anonymous composer.

Currently there are two existing work pages for Arirang listed under their arrangers rather than anonymous:
https://imslp.org/wiki/Arirang_(Kim%2C_Hee_Cheol)
https://imslp.org/wiki/Arirang_(Ossovskiy%2C_Stanislav)

I would have thought there should have been a page for Arirang(Anonymous) under which I could add my arrangement, but another forum post suggested that the policy had changed:
https://imslpforums.org/viewtopic.php?p=37945#p37945

So should I create yet another work page like Arirang(my name) instead of a page for Arirang(Anonymous)?

And, if so, how do I make that work show up under my Arranger tab vs my Composer tab?

@Sallen112 Is this post in the appropriate forum?

So since I made the new category page for here for the Korean Folk Songs. I think all arrangements of the melodies of folk music used from the Korean Region (for both North and South Korea or before 1945 when they were unified) probably should be under this category.

Just need a flag image to be used but there is two current for the North and South.
