Review comment:
Hm...I'm not necessarily that concerned about calling
`mainConsumer.committed` twice in rare cases (although maybe that would not be
so good, since those rare cases happen to be those in which this is probably
more likely to time out, right?)
But personally, just coming into this code from the outside, it's super
confusing to have two different methods for initializing the offsets. It seems
more convoluted that way, to me. Also maybe I am missing some context here but
why do we call `initOffsetsIfNeeded` from `initializeIfNeeded` rather than
from `completeRestoration` in the first place? We don't need to initialize main
consumer offsets until it transitions to running
