For Gaia's nominal sensor, yes, it saturates at magnitude 3 or so. But I think I remember reading that they had committed to doing all the stars, all the way to Sirius. Something they have in their bag of tricks to attenuate the bright ones to bring them into observable range, at the cost of a little extra trouble. Let me check if the bright ones made it into DR2. If so, it should be easy to extract a list of the celestial-navigational stars in their best modern form.
