To understand, these Android API versions are like SDK versions, is that right? Does this basically mean that Android API 21 is the "SDK" released in 2014 as part of Android 5, so basically you'd support using a new libc++ against an Android SDK released in 2014?

What is the intended support policy for libc++ on Android? At what frequency is support for older platforms dropped? I'd just like to make sure that there is some reasonable policy in place to make sure we don't end up having to support ancient SDKs (which often doesn't add much value since mixing a new libc++ with an old SDK is a niche use case). For example, for Apple platforms we officially support only the latest released XCode (with the matching SDK).
