Description

UUIDs are currently randomly generated, which is bad for indexing; specially read and writes access, due to low locality.

If we could add a time component, I think the index churn (amount of writes) would shrink, and lookup would be faster.

It should be fairly easy to verify if that's really true (create a proof-of-concept, and measure).
