Why don't users in the EU have access to Home Screen web apps?
- https://developer.apple.com/support/dma-and-apps-in-the-eu#8
- iOS 17.4 で EU のみ PWA (Home Screen web apps) のサポートがオフになる
- これまで WebKit と iOS が密に結合していることで、権限取得やストレージ分離などが機能していたから提供できた
- 任意のブラウザが入ることで、ユーザの同意をバイパスしたデバイスアクセスや、インストールが発生する危険性がある
- DMA の要件を満たしながら、ここにセキュリティモデルを構築するには Home Screen web apps は使われてない
- 従って EU では PWA を削除せざるをえなかった
