Steam Workshop

One way we could potentially share TSW4 content made with the editor is steam workshop, just like TS Classic mods

 

Steam Workshop is great, but wouldn't work with the Epic or the console versions.

 

Editor made content can't be shared with consoles anyway

 

With a good built-in system it could be possible. They already said that the goal would be to have it integrated with the Creators Club. So the concept is there, but it will be TSW5 or TSW6 by the time we see anything materialize out of it.
