Unless there's a licensing process that makes the agency money or shows up in the numbers they show their bosses (like in this case), no regulatory agency in my experience is ever willing to clarify if something is legal or not. Their only response is to hire legal advice, and they'll take legal action against you if you're wrong. It's stupid that just knowing if the government will let you do something often requires paying money to a private business licensed by that same government for an educated prediction that you could very well still end up being responsible for if it's wrong.
