I agree with you w/r/t the streaming parallelization. I remember huge arguments about this on some of the lists back in the day, because that design decision had lots of ridiculous consequences.

Eg, mutable state capture in lambdas is largely restricted because of the thought that people would use parallel threads within the stream processing blocks. That decision lead to lots of ugly code, IMO.

I've also never seen a need to try to parallelize a simple stream processing step.
