I really don't think maintenance access should be taken away from security and cargo. While I can get people wanting it a bit easier on antagonists wanting to take advantage of maintenance, I just don't think it makes much sense to have that as the only reason to take that access away - and even if it's decided security shouldn't have that access, I really think cargo should still have it. What is there that needs to be taken from cargo being able to go into maintenance? Finding obscure items for bounties? I think it'd really just make cargo somewhat more underwhelming as a job without even giving any other job or role any sort of benefit.
