The problem is that the range can be constructed from a limited set of values, but the actual possible precision of a Timestamp consists of many more possible values.
E.g. 2023-05-26T16:28:46.25Z has a precision greater than second and less than millisecond, but the current way of modeling timestamp precision in the range has no way of expression "2 fractional second digits".
