in 2007 when ios first released, we had the ability to open files without insanities everywhere else. it was total insanity it was not possible, part of the apple thinking that you only do what they 100% say. Who would dare have some video file that isnt in itunes? well certainly not someone the mighty apple cares about. so this lead to movie players also having builtin ftp/smb/nfs clients/servers to be able to access your content, god forbid you could just have files.
so yeah, to have a 2007-vintage API be "legacy that cannot open files properly" is a joke, pretending that it is not, is the apple reality distortion field
