Are HRE marches costing a diplo slot with revoke the privilidgia intended behavior?

[ryak2002]

I thought i had finally come up with a great use for marches. I wanted to turn brandenburg into a march since they were my free vassal, to allow them to take advantage of the military bonuses, but then they started costing a diplo slot even though they were a HRE vassal. I was very disappointed. I'm hoping this was just an oversight. Can anybody confirm if this was intended behavior or should i report this as a bug?

I would imagine this was done to stop you from having the sheer OP-ness of a hundred marches. Of course, you'd pay a cost for that in terms of income, but an HRE march-swarm would be a very scary thing indeed.

Yeah it's WAD. Otherwise it'd make HRE vassals too useful, and you'd also have an option to annex them whenever you wanted...
