To prevent this we check if a provider is a versioned kernel package (like an out-of-tree module) and if so check if that module package is part of the protected kernel set – if not it is probably good to go. We only do this if at least one provider is from a protected kernel though so that the dependency remains satisfied (this can happen e.g. if the module is currently not buildable against a protected kernel).
