A content-based hash would be better as you don't have to keep track of version numbers. It also eliminates the possibility of breaking things by reverting from backup then making further changes.
A lot of systems do this by default, so, e.g., you would have /js/webflow.abcdef.js where abcdef is the content hash.
Code export is not working for clients, without cache busting the assets like .css files.
As of this, I would say, code export is broken for now.
So please add a simple cache busting, as suggested above.
Just appending ?v=hash would be fine.
