@ericniebler do I understand correctly that the 0 case is not supported? (I'm deducing from the PR, as the title is a bit unclear to me). If so, I think this is fixed in the wording of R10: https://cplusplus.github.io/sender-receiver/execution.html#spec-execution.senders.adaptor.when_all (actually, I think the behaviour for 0 is not specified in the design, but we're passed that and in the wording stage anyway).
