I have heard stories going both ways to be honest. I have heard one story of a guy wanting to leave, then being asked to pay it back, basically saying "show me the document that makes me pay it back" and ASA could not produce it.
Though a more recent story I have heard suggests that another person stayed because they were going to enforce it.
I would suggest that if you are talking about something "in the future", they will fix any loop holes by then because of "Story A" above and/or the Global shortage of Controllers.
If you are in and want to leave, PM me with your details and I'll give you more specific info.
