I don't think so. The code calls stat() or blkdev_get_size() to get
size if the size argument is zero.
Please, use BLKID_DEBUG=0xffff env. variable to debug libblkid.
It prints
"ready for low-probing, offset=%zd, size=%zd\n"
after initialization.

try ./shlibs/blkid/samples/superblocks <device>
this sample program uses only superblocks probing and the prober is
initialized by blkid_new_probe_from_filename() where we call
blkid_probe_set_device(pr, fd, 0, 0)
and it works for me:
BLKID_DEBUG=0xffff ./shlibs/blkid/samples/superblocks /dev/sda3 | grep ready
ready for low-probing, offset=0, size=2410007040
