Jc3s5h added a comment. Exact numbers can occur not only through counting, but also through definition. For example, as explained by the US National Geodetic Survey <http://www.ngs.noaa.gov/PUBS_LIB/FedRegister/FRdoc59-5442.pdf>, one yard is defined as exactly 0.914 4 meter. One could imagine properties in Wikidata where most of the instances are measured, and have an associated uncertainty, but a few instances are defined, and so are exact. So unless it can be proven that a certain property is //always// uncertain, or //always// exact, the property should be designed to accept either the proposed number type, or QuantityValue.
If it isn't possible or practical to make properties take either kind of number, I don't see any choice but to use QuantityValue with amount = lowerBound = upperBound.
