+* inject-thrift-client: Deprecate `c.t.inject.thrift.AndThenService`, `c.t.inject.thrift.modules.AndThenServiceModule`, 
+  and `c.t.inject.thrift.internal.DefaultAndThenServiceImpl`. These were plumbing for unreleased
+  experimental record/replay functionality and currently do nothing with no plan for implementation.
