Subjectwhat is "temporary" about code in "__register_chrdev_region()"?

i was just perusing the code for that routine in fs/char_dev.c and
noticed the label that some of that code was, well, temporary:

/* temporary */ [line 99]
if (major == 0) {
for (i = ARRAY_SIZE(chrdevs)-1; i > 0; i--) {
if (chrdevs[i] == NULL)
break;
}

if (i == 0) {
ret = -EBUSY;
goto out;
}
major = i;
ret = major;
}

so what's "temporary" about it? that it can (dynamically) handle a
major number of zero? is that supposed to represent a first step in
migrating to alloc_chrdev_region(), or what? i'm just curious,
