c48196c is responsible for a regression on a micro-benchmark:

Is this concerning?

Hm, I reverted c48196c, and it didn't seem to make a difference, at least on master branch. I'll leave it to you Rafi in case you do wanna look closer into this - it's possible that we have fixed a regression that was exposed by this PR in some other way.

Thanks for the investigation! I will explore it a bit later, but probably won't probe too much deeper
