I'd like to see the importantSubscription re-implemented as a way to validate the route being correct for a message on the same topic alongside match/priority

var bulkSubscription = &common.Subscription{
PubsubName: "messages",

As my previous review - the validation of arguments passed to these parameters should be implemented as per the implementation spec. I do think that this is something we need to address both sdk-side and in the runtime explicitly as part of best practice.
