Since iOS 11.3, the apple-mobile-web-app-capable meta tag should no longer be necessary, having been replaced by the display: "standalone" property in the webmanifest.
However it appears that without this meta tag, the splash screen images (<link rel="apple-touch-startup-image" .../>) don't appear.
Either the guidance in the above linked article is wrong, or it is a bug in iOS (tested in v15.4)
