It's news to me and it's not listed in the Gnulib portability gotcha list.

What happens if you run the attached program on macOS? It creates a file 
"file" and then tries to access it as a directory, which should not work.

#include <unistd.h>
#include <fcntl.h>
#include <stdio.h>
#include <sys/stat.h>
#include <errno.h>

static char const *names[] = { "file/", "file/.", "file/./" };

int
main (void)
{
  struct stat st;
  int i;
  if (open ("file", O_WRONLY | O_CREAT, 0666) < 0)
    return perror ("file"), 1;
  int status = 0;
  for (i = 0; i < 3; i++)
    {
      char const *name = names[i];
      if (lstat (name, &st) == 0)
	printf ("lstat succeeds on \"%s\"!\n", name), status = 1;
      else if (errno != ENOTDIR)
	perror (name), status = 1;
      if (faccessat (AT_FDCWD, name, F_OK, AT_EACCESS) == 0)
	printf ("faccessat succeeds on \"%s\"!\n", name), status = 1;
      else if (errno != ENOTDIR)
	perror (name), status = 1;
    }
  return status;
}
