To me it feels incredibly wasteful as this is addressing artificial problem and then will have to catch up with Apple moving goal posts. Sure the authors can gather some experience with software development, but other than that it sounds like a huge time sink for no real benefit as Apple can always shut it down one way or another. I would rather see people working on an open fork of Android and address real issues like the fact that Google removed call recording API from Android, to help insurance and other phone sale companies scam their customers, as they can no longer record telemarketers lying to them.
