Correction, not agreed. I forgot what I initially had in mind as being
the main obstacle to storage of computed intermediates, i.e. fetch
provoding no cdef.

While you can perform various computations on your input with graph
via cdef, I don't see a similar facility coming with fetch and/or
companions. So apparently, there's no way to stash those computed
results away in an RRD.
