Subject: [PATCH] Try alt index (#1927)

* Try alt index

* This is one of the last recommendations that mLabs said to try.
* Also paired with re-investigation mentioned at https://github.com/OpenUserJS/OpenUserJS.org/issues/1825#issuecomment-1007206823

* Index reordering again

* Seems to be happier. Not quite the ESR rules because isLib has to be first and in those locations or the index never gets used... more likely boolean equality, semi-static preferred equality, semi-static less preferred equality, etc.
* We'll try this for a while.
