feature:Events: [botocore] This migrates the event system to using sevice ids instead of either client name or endpoint prefix. This prevents issues that might arise when a service changes their endpoint prefix, also fixes a long-standing bug where you could not register an event to a particular service if it happened to share its endpoint prefix with another service (e.g. autoscaling and application-autoscaling both use the endpoint prefix autoscaling). Please see the upgrade notes to determine if you are impacted and how to proceed if you are.
