I haven't studied this draft in detail, but I believe that it would be good
for this WG to work on blind signatures, as they are a primitive with a lot
of applicability.

In general, I'd probably be more inclined to select blind BLS for new
applications, but there are certainly going to be a lot of settings in
which people don't have pairing code, and in those cases, it seems like
this draft would be valuable.
