I have that same assumption but I would rather have actual facts. Also those quest are said to be for just FS so that could mean that only FS will be allowed on those planets, but once again those are rumors and not facts..;)
I am asking so that I know for certain and there for can plan accordingly
How about you wait for actual information from the admins to come forth as to what the planets will be used for, etc. If nobody has the info you can't plan, and they wont release said info until they are ready to. So be patient.
Admin planets follow the same rules as every other planet in game there is no exemptions. On that note no admin, that I know, will ever grant anyone permissions to arrest and/or execute on their planets
