To be exact, I don't think all the bindings have to be *declared* in the
same Gin module, but they do have to be *known*. IE., in the above
snippet, CustomerAccountsServiceConsumer
& CustomerCreditCardsServiceConsumer can be declared in any module, but
one module must have the @Provides Set<ServiceConsumer<?>> and know about
all the of them in order to provide it.
