I don't intend to sound mean or judgmental, but these questions won't teach you anything. The most likely answers are either bold face lies, or a dodge.
I mean no offence and judge no-one, but ulterior motives are common at that level of backing. Blimey, I would be disappointed if the leaders weren't doing what's in their best interests.
If they say they will, then that means they want to attract more mayors/barons. However, there is a good chance that they will also secretly send out messages to their high ranking supporters, saying they will support them.
They could say they won't, which means they want more counties and duchies.
Either one has a high likelihood of being a blatant lie. A leader wants to replace his followers frequently, so they cannot conspire against him/her.
The most likely response will be to dodge the question by saying something like "We will be sure to allow and encourage players to replace NPCs."
In the end, the thread just becomes a more complicated version of Clue.
TL;DR
This is a very politically charged question that is unlikely to result in honest answers, and the few honest answers will be indiscernible from the falsities.
