Hi @Gmantiqueira!!

About allowing JS files:
Our client uses a third-party app (Pushnews) that requires a service worker file in the same domain to work properly.

About the creation of folders inside the public folder:
More folder structure flexibility and maintaining the same behavior observed in VTEX IO, like the sitemap and XMLData files.
