After further research, I found some preliminary analysis:

http://libfslibs.googlecode.com/files/Resilient%20File%20System%20(ReFS).pdf

which is the best we have to go on so far.  There is no superblock as
such, but there is a level 0 metadata block.  In any case that
analysis agrees with me that you should just check the first 8 bytes
of the filesystem / partition.
