When I've talked to senior researchers about these problems, they say that they have no problem finding distilled information about new results; they get it from in-person conversations at conferences that they attend frequently. The publishing of distilled research would most benefit low-status, newer researchers (like Ph.D. students), but it needs to be valued by senior researchers to make it into the incentive systems of hiring and grant funding. It seems like a tricky problem to fix the incentives here.
