Hi @vasia ,
There was no clear rejection in the discussion, so I thought I'd try my
luck :)
This technique could be enabled by using a flag only if we introduce a node
split version of all the library methods. Otherwise, for newly written code,
users would still have to pass a combine function according to their algorithm.
They'd also have to pass the threshold that differentiates high-degree vertices
from low-degree vertices. What is more, they still need to split and aggregate
before and after each step.
These are aspects that cannot be guessed and that highly depend on the
algorithm.
Also, what I had in mind regarding this PR was that we would discuss and
try to improve the code a bit, rather than immediately discarding it :(
