If you will have any follow ups, please send as separate PRs. 
Such larger changes may need some time to sink in, and sometimes got reverts due to failures on some weird CI bots. This probably should be safer since it's not OS/arch-specific, but still there are some changes of breakages. So it's better to merge it sooner rather than than later.
