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 <stdio.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;
}
