If I understand correctly, then it is exactly this use case -- 
specification of options in fstab -- that is the primary motivation for 
Ben Slusky's patches.

Otherwise, an external hash program can be performed with a pipe using 
file-decriptor zero, I do this myself:

# gpg -d password-foo | losetup -p 0 -e encryption-algorithm...


I think that being able to specify options in fstab can offer 
more-simple system configuration (as opposed to scripts such as the 
crypto-swap script). People can still rely upon such scripts, of course, 
if they prefer.

Sorry if I'm stating the obvious here...
