Perhaps, but that's pretty much coining a new term, which we would then have to explain. And since the opposite would be "dead API", what is a dead API exactly? And doesn't it follow that all APIs are living? If we stick with unstable, we're adopting a term that's in use by at least one other language community (Rust), and the slightly negative connotation is welcome -- people should think twice before using unstable APIs.

I read somewhere that the term "stable" means "dead" in some contexts... was it maybe a medical context?  So "living" would be "unstable" too, as Tim suggested.

And since people know what a living document is, a living API wouldn't be much of a stretch.

On the other hand, "unstable" carries a bit more connotation of "needs caution".
