Unless the same xtal drives a UART or some other time critical device.

UART comms can accommodate a total ( tx+rx) error of at least 4%, so the ~0.01% error would be insignificant.
For anything other than long-term timekeeping or frequency measurement, 0.01% error is well below the weeds
westfw:
Note that the difference is about 0.01%, which is less than the tolerance of the ceramic resonators used in many modern designs, and probably on the same order as the tolerance of random cheap crystals that you buy from China.It's really hard for me to imagine a "normal" application that would care about that level of error.
