Complex widgets for Calendar spinners or diagrams are out there on GitHub. An effort to bring these together is lacking, and I reckon that if all these things weee brought together it would definitely encourage more developers to dive in.
I find this to be the case with a depressing amount of Google code. They do not seem to have a culture which values not breaking their users' code.
Under language goals on their readme,
> We also have explicit non-goals for Carbon, notably including:
> * A stable application binary interface (ABI) for the entire language and library
> * Perfect backwards or forwards compatibility
There's also this blurb
> Our goals are focused on migration from one version of Carbon to the next rather than compatibility between them. This is rooted in our experience with evolving software over time more generally and a live-at-head model. Any transition, whether based on backward compatibility or a migration plan, will require some manual intervention despite our best efforts, due to Hyrum's Law, and so we should acknowledge that upgrades require active migrations.
