[PATCH v2 0/2] Update documentation/discoverability around `scalar`

A couple of changes following on from a discussion around the discoverability of `scalar` config changes[1].

Following that thread, I was additionally working on a patch that would involve commenting each of the changes and why they're set. But that was taking me longer than expected so I figured I get these smaller changes up rather than waiting to complete everything.
