Used that as a replacement for momentjs until we had to make things seriously timezone-aware, and some quite crippling tz bugs (granted, probably 2 years ago now) made us move to Luxon. That worked well, but I'm glad to have something JodaTime-ish coming now that doesn't conflate instants with zoned datetimes with durations.

It’s not really the same thing though, right? It doesn’t handle instants vs zonedtimes etc.

Even the simplest of future cases is handled poorly by these other libraries. If you want to say that something happens on a certain date in the future (say, a due date), your only option is to use an instant as an approximation (often midnight utc on that day). It works ok, but you’re better to have a proper datatype that represents a day without a time and timezone component (it’s effectively a 50hr ish window). Temporal gives you all that and more.
