Buildroot-only modules

Some modules are built in MBS/Koji but are never released to users. Currently such modules can only be used as build dependencies of other modules. In future, if solution like "ursa-major" [1] is implemented, such modules could also be used as build dependencies for non-modular packages. An example of buildroot-only module is javapackages-tools. This module is used as build dependency for 4 modules, but it is not included in any compose and it's not shipped to users. Should such modules be considered as allowed in Fedora? I am not aware of any policy that would disallow them, but I would rather ask in advance and not be surprised if one day I find out that I have to ship such modules to users and support them.
