It got a little bit better, first with trains (bundling together PRs so they weren't going out one at a time), and then the merge queue started automating most of the testing and fitting together PRs into bundles that could go out together. But by the time I left GH last year it had devolved into roughly the same amount of hassle; I had multiple days where I could queue a PR for deploy mid-morning and not have the deploy containing it go out until dinnertime, and I'd need to keep an eye out in Slack in case merge or test conflicts arose.

well, that’s horrifying! I appreciate the update though
