Apache Karaf -> Spring Modulith migration

[vfedoriv]

Let's say we have an app with a structure based on Karaf modules (bundles) and want to migrate it to Spring Modulith.
And let's assume we will take care in some way with maven dependencies/build modules.
But our app has two parts, common (open source) and additional (commercial), each based on different namespaces (org.mycompany and com.mycompany).
How we can manage this in Spring Modulith (as I understand it requires a common root package)?
