In the recent change, https://dart-review.googlesource.com/c/sdk/+/503040, the asynchronous nature of the change required adding _new_ hooks to track that the plugin isolate is analyzing or not. I missed removing the old hooks. The result is that an invocation of `dart analyze` will get a notification from the plugin isolate that it is analyzing, and then _immediately_ a notification indicating that it is not. So this change removes the old hooks.
