Let's make sure it's still protected by basic auth using the variantId, we need to know which variant is hit. 

Skipping the registration endpoint we might miss metadata, like os version etc ... But for this first version it should not be a issue.

The iOS push SDK could call a (private) method and just deliver the metrics related info - that's splits the concerns and removes the need to call register endpoint on places where we do not really need it
