I forgot about the similar one in the library source tree
https://github.com/boostorg/geometry/blob/1243579bf071e1f51eb02897e05aa7ffe20ff69a/include/boost/geometry/index/detail/rtree/utilities/statistics.hpp

Here you can see how to call it
https://github.com/boostorg/geometry/blob/793345358c28ad0f18cc02e9c62ce18ebb61247b/index/example/serialize.cpp
