Stars are not included by default, meaning they will disappear for
existing users without a schema migration. We can't add a schema
migration in a release branch, so we can't add this feature in
stable-2.15. In master, revert it to avoid breaking existing users
of googlesource.com.
This reverts commit f5f89beb70.
