There's a few negative results journals now - https://www.negative-results.org/ https://www.negative-results.org/ for example. The only concern I have around a disincentive to not publishing is that in some fields, the peer review process can be quite flawed and effectively hold back worthwhile publications for various reasons - sometimes there's too much of an expectation of specific ingrained methodologies, or an expectation of certain "doctrines" to be adhered to. There can also be some significant gaps between disciplines, where neither discipline wants to publish the work, as they both feel it belongs in the other discipline, which effectively leaves only the more generic (and usually less prestigious) "any inter-disciplinary research" journals. That becomes a problem if institutions are focused on publication metrics and venues as a priority, as it means the institutional incentives drive people towards or away from these kinds of work. Ideally we need negative results published in the same venues as positive results (in my view), so those doing this valuable work don't get "relegated" to the negative results journals, which will no doubt get less attention at tenure review time, or from grant funders looking at publications etc.
