The Java parallel is apt. Joda-Time dominated the ecosystem for about 8 years before JSR 310 landed in Java 8 (2014). One thing that helped there was a clear, single release target.
What I keep thinking about with Temporal is the adoption timeline question isn't really 'is it specced?' anymore, it's 'what minimum runtime version do I need?' Node.js, Deno, Bun all need to ship it stably, and then the practical floor for usage is wherever most prod environments are. The polyfill situation (@js-temporal/polyfill and others) doesn't really collapse until that happens.
So the speccing is done but I think we're still a couple of LTS cycles away from it being genuinely boring to reach for Temporal.
