@fg1417 Thanks for your responses!

I realized that going at this pace it will take me a while more to dig through everything. I'll still have to continue at `fix_data_uses_for_vectorized_drain`. But for now, I'll run some testing and benchmarking., and continue the review in parallel as I have time.
