Realistically, that means the best we can do is:
* Ensure that, at any point in time, any _new_ connections will succeed. There is no period where new connections are dropped.
* Provide some period of time for the old Ztunnel to continue processing any established connections.

If this period of time ("drain period") is longer than any connections, there is zero impact on applications at all.

   * We'd just use PackageSanityTests directly, saving us from needing this separate type, but we're
   * currently skipping MediumTests on Android, and we skip them by not making them present at
   * runtime at all. I could just make _this_ test a MediumTest, but then it wouldn't run on
   * Android.... The right long-term fix is probably to get MediumTests running under Android by
   * default and then suppress them strategically as needed.

3.  Guava has one dependency that is needed for linkage at runtime:
    `com.google.guava:failureaccess:1.0.2`. It also has
    [some annotation-only dependencies][guava-deps], which we discuss in more
    detail at that link.
