Description

Once we have a Poplar1 specification (https://github.com/cfrg/draft-irtf-cfrg-vdaf/issues/84) and implementation (https://github.com/divviup/libprio-rs/issues/141), we need janus to support it. Of course, a DAP implementation should be generic over VDAFs, so we shouldn't need any Poplar1 specific code, but what we will need to do is teach Janus to deal with VDAFs that actually have an aggregation parameter, where aggregation jobs cannot be created or driven until the collector hits [leader]/collect.
