Not only this, but would also provide the mobile players with the ability to use those things.
I'm a PC player, so I don't have that issue, and I know that once upon a time Android users at least could use them. This is the obvious work-around for solving those new mobile platform limitations.

Something I pitched to Sony that I'll pitch here as well since it's now that same situation with mods...
If you include a ton of "dummy files" in the game, which are zero KB in size due to having no content, these can be used as ways to load mods since those dummy files would not be added after the fact. A mod is selected on the website and then downloaded in the same way a shared creation is, and saved that way, replacing these dummy files with the mod's code/files. Basically, mods become DLC in a way.

I suspect if games like Roblox can incorporate a built-in system to let users create minigames (""experiences"" as they're defining them lol), there's no reason Jundroo shouldn't be able to figure out a similar work-around. Amirite?! :D
