that floating well might be used for isolating noise...and power supplies are noisy...
hence, connecting the well to the power supply will just make the well noisy...

Sometimes floating wells help you to avoid the body effect of PMOS transistors by connecting the source and the bulk tie together. The body effect increases the threshold of th transitor which impacts the performance of the transistor.
