You will lose one type of negotiating leverage and gain another. Once you have been there a while your true value will be obvious (especially when you produce, in a _nice way_, comprehensive documentation at your first performance review). Please be clear that I am not advocating salary blackmail (pay rise or I quit) tactics. However reasonable and friendly negotiations periodically is not an unreasonable thing to request. For most of us the company at hiring time is seeing a choice beteen you (an unknown risk) and someone else (also an unknown risk) and while they obviously have a preference it may not be that strong. However after twelve months they will be evaluating you (a known, and hopefully respected, certainty) and someone new (an unkown risk) which is a whole different game.
