The Cartesian decomposition part of the MPI spec does not seems to be
present in boost mpi.
Is it just due to a lack of resources or is it useless for some
reason ?

I'd like to look into it but would like to make sure there is a
point.

I think you’ll find that most codes perform parallel decomposition using other tools (e.g. Geometric, Graph, Hyper-graph, etc…) partitioners so this particular MPI capability isn’t as broadly useful as other approaches.  I suspect that’s why it was never implemented.
