Hi [~aholler], Yes I agree there are representation issues, on the other hand a spark specific
model format locks you in.

I dont know if PMML is a lost cause but at least you can get it running also on limited devices
that dont run Spark.

Also I understand that if the focus is on improving the internal format then makes sense.

> The improvement opportunity exists in all versions of spark.  We developed our set of
changes wrt version 2.1.0 and can port them forward to other versions (e.g., we have ported
them forward to 2.3.2).
