I'll investigate the other topics you raise, but I should point out that the results of this test are the same as for the mainline except for the last two good paths

        list.add(Arguments.of("\\\?\\C:\\Users\\file.dat",
                              "C:\\Users\\file.dat"));
        list.add(Arguments.of("\\\?\\UNC\\localhost\\C$\\Users\\file.dat",
                              "\\\\localhost\\C$\\Users\\file.dat"));

which fail with the mainline.
