Tumblr user suggests:

"Itch.io should have a steam workshop for games and Crucially it should not be restricted to popular games or computer games. I want to submit a 2 paragraph text document as a "mod" for somebody's 10-page indie rpg

"ok but crucially I want it to show up as a tab on the original itch page like the steam workshop does. bc i feel like distributing it as my own thing is 1. wildly passive-aggressive and 2. doesn't get eyes on it. whereas being like 'a mod to fix the dice mechanics in this game' is 1. only very passive-aggressive and 2. gets much more eyes on it"

Obviously since I'm sharing this here I second the idea. I imagine people publishing on itch could be presented with an option to enable a workshop which triggers an additional terms of service clause allowing workshop works to be safe from any prosecution.

Unlike Steam, itch.io lets anyone publish a game without prior screening, and projects other than games have been allowed for years.

This is more about letting people tack them onto a page attached to the existing media they're related to, similar to the steam workshop, I think. Not just about publishing them in general.
