(I work on a project that uses Chromium’s commit queue infrastructure)

I think there’s a big difference between Chromium’s approach and the “not rocket science” rule. AIUI Chromium’s model there are still postsubmits that must pass or a change will be reverted by a group monitoring the queue. This is a big difference in practice vs having a rotation or team that reorders the merge queue and rolls changes up to merge together. In the commit queue model you land faster at the expense of more likely reverts than in the merge queue model.
