EventBus in 8.3

Module Development
1

According to the 8.1 to 8.3 SDK,

modules still using the EventBus class must switch to the EventManager implementation

I note however that in 8.3.2, the PerspectiveContext still contains:

EventBus getEventBus()

Is it ok to continue to use this interface?

It seems this is the only one left - there were EventBus instances available on Session, InternalSession, Page, and View that were all removed.

I'm not sure if the team just forgot to come around and get rid of it or what...
