Hmm so reverting the CL also causes a perf regression ¯\_(ツ)_/¯

 Issue 779551  has been merged into this issue.

 Issue 779550  has been merged into this issue.

Looks like these metrics were improved when the original CL landed, and now reverting the CL is bringing them back to the original state. There were other metrics harshly affected by the CL, so we want to have this revert CL in. Closing as WontFix
