I don't know if that's totally fair to Chrome. The specification was undergoing a lot of changes at the time, and V8 decided to wait for the specification to stabilize; meanwhile, Anba kept working on the implementation for FireFox. Additionally, the version of Temporal that Deno exposed last year was the heavily out of date to the most recent specification and had a large portion of the specification that was not even implemented.
