You wouldn't get warned for no reason, you clearly did something wrong that the staff in question deemed it was worthy of you receiving a warning. If this were to get accepted it wouldn't make sense and if it were to happen it would spark a mass amount of other unwarn requests. Makes no reason for them to be removed.
Also as Ethan says you having warnings that are old don't really say anything as there are staff and eps that have warnings already. And got into the teams with these, the warnings are old and you've probably improved since then so you don't really need to worry about them.
