"Default configuration parameters" are not mentioned in it,
but src/sbin/newfs.c says:

---
	if (mfs && !strcmp(special, "swap")) {
		/*
		 * it's an MFS, mounted on "swap."  fake up a label.
		 * XXX XXX XXX
		 */
 :
		mfsfakelabel.d_partitions[0].p_size = 16384;
 :
		pp = &mfsfakelabel.d_partitions[0];

		goto havelabel;
 :
havelabel:
	if (fssize == 0)
		fssize = pp->p_size;
