Thanks for the reply 
We did get a couple of emails with questions - I replied with screenshots and info on our use-case.
I understand re: it taking time, fair enough
Hoping (fingers seriously crossed!) for a swift review as we’re already using the standard API and have a pretty clear use case (I hope, hope I did a good job of explaining!).
We actually have an event coming up really soon that we’re hoping to use the Premium API for, but unsure if we’ll be approved in time (our devs have been looking over the docs already in prep - but thanks for the links, I’ll pass those on).
Thank you again for taking the time to reply, appreciated. We’ll just keep our fingers, toes, and beaks crossed for a swift approval! (appreciate everyone is probably hoping for this though, ha!).
Cheers 
Mike.
