That's why I said 'found their way'. It would just be a matter of training and infrastructure to make the process efficient.
Example: an internal 'is this one of the coolest apps you have ever seen?' option given to all app reviewers. One guy whose job it is to review all apps where that box was checked. If he agrees, he sends them on to somebody on Jony Ives team. If they agree, they send it on to Jony.
Frankly, outside of a keynote with an audience expecting to be impressed, I doubt a weather app would get a thunderous reception.
At the end of the day, that is just a weather app with cool graphic and the guy reviewing apps probably sees a shit ton of those per week. It would take something significant or sufficiently unconventional for him to start a buzz inside Apple.
(BTW: not criticising the guy, he is a dedicated developer and Apple let him down. But let's keep stuff in perspective)
If such an option did exist, no way this app would be cause to use it. There are many other weather apps which have similar use of animation, such as Magical Weather. This app is not particularly unique or innovative.
