+As an example, if `/test` were introduced in v1.1, deprecated in v1.2, and removed in v1.3 then an
+implementation can support v1.1, v1.2, and v1.3 by implementing `/test` as it was defined in v1.2 (minus
+the deprecation flag). If the implementation wanted to support just v1.2 and v1.3, then it could
+optionally implement `/test`, though is encouraged to. Further, if the implementation only wanted to
+support v1.3, then it *should not* implement `/test` at all because it was removed.
 
 Generally deprecation is paired with replacement or breaking changes. For example, if `/v3/sync` were
 to be modified such that it needed to be bumped to `v4`, the MSC which does so would deprecate `/v3/sync`
