It looks like draft-irtf-cfrg-ristretto255-decaf448 was just updated to bump the date. It seems to me the draft is feature complete, and it has a number of different implementations available. It is also a dependency for a number of ongoing CFRG drafts, including darft-irtf-cfrg-voprf, draft-irtf-cfrg-hash-to-curve, and (most likely) draft-irtf-cfrg-frost. 

What remains for this draft to move forward? If nothing, perhaps we can start RGLC and move this document along in the process?

Best,
Chris
