The FAQ https://rs-archive.github.io/faq.html is pretty clear about what they're used for:

> They contain all the various raw assets used in the game (e.g. maps, models, sounds) and the definitions of content like NPCs, Items, and scenery objects.

For archival purposes, as the name implies. I don’t understand why you try to stir something up.
