Module access - deny by default option?

[ghferrari]

First of all, thanks to the Spring Modulith team for this great package :-)

If I've understood the documentation for version 1.2.5, Spring Modulith currently uses an "allow-by-default" access model i.e. access to other modules is allowed unless explicitly restricted.

Is there a way to switch to a "deny-by-default" permission model? In this scenario, access to other modules would be forbidden by default unless specifically granted?

I think this would be a useful feature.
