Really need to make a decision about making a push for EventBaseManager everywhere. Getting/setting EBs when there's only ever one seems so silly, but in (e.g.) tests where one-off EBs are used without using the EBM, stuff like this will break.
Test Plan: definitely compiles and sorta works, will write unit tests if the dust settles
