They're Java-only APIs and since Syncthings core isn't written in Java, the author would have to write JNI glue to call Android when writing/reading files (and honestly this would be quite tedious, because the way SAF works is to assign Uris to each file and you need to keep querying it to get folder structure since you can't just concat paths like with files).
The author didn't want to do that and tried to persuade Google to continue letting them access all files, all photos and all documents directly and Google said no. That was the "difficulty" - turns out it's really hard to publish on Play if you refuse to follow the guidelines. Just like on AppStore.
Android Apps are and mostly always have been restricted to the Java virtual machine (or its modern equivalent) exactly because that makes them portable between sometimes quite different base systems from different vendors. If you insist that makes it less of a Linux system I'd like to know what you think of flatpak apps on top of immutable distros. I hope you agree that, conceptually, they're quite close actually.
Nothing of that is expected to be supported on NDK, at least officially, Google and partners have the freedom to break those expectations as much as they feel like it.
Fun fact: the official Dropbox Android app used to use inotify to watch for changes to the publicly writeable synced files in order to sync back to the cloud! Had to be replaced by java Storage Access Framework APIs later.
Another fun fact is that the Android sdk came with a JNI wrapper around inotify but it buggily stored inotify handles in a static (global, within an app vm) dictionary, meaning you'd silently lose tracking if you created more than one Java file watcher object that happened to be for the same path, so I had to rewrite that JNI wrapper back in the day to avoid that global state bug.
Many computer users run a modified version of the GNU system every day, without realizing it. Through a peculiar turn of events, the version of GNU which is widely used today is often called Linux, and many of its users are not aware that it is basically the GNU system, developed by the GNU Project.
There really is a Linux, and these people are using it, but it is just a part of the system they use. Linux is the kernel: the program in the system that allocates the machine's resources to the other programs that you run. The kernel is an essential part of an operating system, but useless by itself; it can only function in the context of a complete operating system. Linux is normally used in combination with the GNU operating system: the whole system is basically GNU with Linux added, or GNU/Linux. All the so-called Linux distributions are really distributions of GNU/Linux!
