If it's going to be supported from underneath has the glue dries why not figure out a way to leave the supports in permanently so this can't happen again? Might not be easy I understand. Perhaps the permanent ones would have to be added afterword and not hold the total weight but, they would help.
Nothing wrong with a bit of overkill, if it makes you feel better, but it isn't necessary. If the mating surfaces are clean, and the sink properly tensioned into position with the temporary props, it's just fine. As in, removing it will involve a, hammer, flat bar, a utility knife to cut the silicone, and a lot of sweating and swearing. Remember, they glue airplanes together, and they don't fall out of the sky due to adhesive failures. The sink will be just fine without a bunch of scrap wood screwed to the bottom of it.
