I don't see any reason it can't be done, either, in theory, and that's with the manual approach. Fancier ideas are viable too, but 500k is still relatively tiny

I don't see any reason it can't be done, either, in theory, and that's with the manual approach. Fancier ideas are viable too, but 500k is still relatively tiny and a manually tractable number. Incremental reviews starting today by many coordinating groups in the node community would take a while to complete, maybe a few years, but with some sensible ordering heuristics like e.g. the most downloaded first, or the most suspicious names first, some value could be produced quickly. But it won't happen, package vetting isn't really a value in these communities. (And that might not really be a bad thing, at least for now...)
