For a partitioned table this value has to be true. For a normal table when setting this value to true, it should at least make sure that the table has at least one child. Otherwise it should throw an error. Blindly accepting the given value may render the statistics unusable. Prologue of the function needs to be updated accordingly.

I can see rejecting non-inherited stats for a partitioned table. The reverse, however, isn't true, because a table may end up being inherited by another, so those statistics may be legit. Having said that, a great deal of the data validation I was doing was seen as unnecessary, so I' not sure where this check would fall on that line. It's a trivial check if we do add it.
