Students putting things on their CV have to make a call between Peer-reviewed and Non-Peer-Reviewed contributions, so we should be clear about what kind this is.  Calling it a proceedings of a conference makes it sound like peer-reviewed for computer scientists, but not so much for people from other sciences.  My understanding is that we are going to provide hosting for supplementary material for a talk, with a DOI.

If, like this year, there is meant to be a follow-up special issue from some Journal in which "the year in SciPy" will be published after formal peer-review, then it should be mentioned here as an additional incentive to put up a paper. Is such a special issue planned, and meant to be an annual thing?
