In KF5/alkimia there is the following code that is used to obtain updateable new entries: 

connect(m_engine, &KNSCore::Engine::signalUpdateableEntriesLoaded, this, [this](const KNSCore::EntryInternal::List &entries)
    {
...
    });

which is triggered by 

connect(m_engine, &KNSCore::Engine::signalProvidersLoaded, this, [this]()
    {
         m_engine->checkForUpdates();
    });

This is required to display updatable new entries for online course sources in the interface when KMyMoney is started.

Unfortunately, in KF6 these methods and signals have been removed from KNSCore::Engine, so that users of the application can no longer be informed about corresponding updates. How can this restriction be removed?
