 In many imagery dataset, it is common to need to slice off a large (or
 small) value and any other value above (or below) into NODATA/NULL values.

 r.null could be extended to perform this operation.

 Flag would transform setnull option value into the lower boundary (if
 "more than" flag) or upper boundary (if "less than" flag) threshold to
 make null values.
