The way the default rules are written make think we match recursively, on full path, but the rules are misleading.
In fact, the regex is only called on root elements of the crate (and not recursively).
This behavior does not work well with our nested modules.
We tried to build a "deny list" but negative lookup ahead are not supported on Nix.
As a workaround, we have to register all our submodules in this allow list...
