[Cthulhu_]

This is what we did for a while at a project; there's options in most git hosts nowadays that force any PR to be up to date with master before merging on the one hand, and to have a green pipeline on the other. That works fine for smaller projects, but because it's not automated you end up with quite a bit of manual labor (rebase on master, push, wait for CI, discover someone else merged into master first, repeat).
