Currently, when we @deprecate an API element on master, the element is stripped from v2. Once we GA v2, we can no longer strip these elements, as they would be breaking changes for v2 APIs.

We need to define and implement a strategy for how to continue to deprecate elements on master post-GA release, without stripping these elements from v2.

One approach might be a deny-/allow-list of deprecated elements. Other, more creative approaches, welcome.
