[*] "Notarization" for iOS is a misnomer and imposes a laundry list of requirements in addition to "the app isn't malware". The guidelines aren't even a separate document; they're quite literally a subset of the App Store guidelines (notice the "only notarization requirements" checkbox):
https://developer.apple.com/app-store/review/guidelines/
Compare that to the macOS notarization requirements, which are quite succinct and are anything but a subset of the macOS App Store guidelines: https://developer.apple.com/documentation/security/notarizin...
(macOS of course still allows you run apps that aren't notarized after passing through several scary warning screens.)
These extra unnecessary guidelines, along with the fact that you still need a paid Apple Developer account at $100/year to submit your apps for notarization (even if you just want to use them on your own device and distribute them nowhere), shut out FOSS entirely and render the DMA nearly useless from my point of view.
