Paddy Horan commented on ARROW-6718:
I would love to get back on stable. I added a feature to disable explicit SIMD
to try and make progress toward this goal. Although the main thing we need is
specialization on stable.
If we can get the same level of performance then I'm all for removing
packed_simd. At the time we adopted it, the author was trying to get it
adopted into std. Since then he has stopped driving this forward until other
features land.
I'll take a look in the next few days to compare performance, etc.
