The chicken-and-egg problem illustrated in this thread seemed like the most appropriate place to highlight: So (see disclaimer at the end) there is a publication I appreciate called Seeds of Science. My understanding is that it is (in part) intended to offer a pathway to work around structural failure in comventional peer review; As its web page describes:

" What is a 'Seed of Science'? It is a speculation, an idea for an experiment, a novel observation, a thought-provoking question and discussion, the highlighting of an under-appreciated problem, or an unorthodox research study"

They got an ACX Grant last year from AstralCodexTen to pursue this.
