The Holy Roman Empire and the 'Occupation of Rome' triggered modifier

[HerraSG]

I find it a little bit strange that the HRE suffers from the 'Occupation of Rome' triggered modifier. And I mean after actually passing the final reform in the centralization branch and tag-switching. I thought Groogy made a note about changing that during one of the feature streams before Emperor launched.
Austria also has a mission in their mission tree that requires Rome to be a part of the Empire and while this doesn't directly support the argument for removing the modifier for HRE, it certainly seems to point to that direction.
