If it is the Classic Vibe or one of the other better models then it is worth doing up. If it is one of the cheaper Squier ranges then no. The Classic Vibe, Vintage Modified, and various signature instruments are generally good instruments. The nut and wiring seem to be the weak points but are easily replaced. If it was a model with a tremolo like a Strat I might be more cautious but a Tele should be fine in terms of hardware, as long as it is one of the better models.
