I often stack PRs to emulate the practice described by Mitchell but it's not ideal as if you need to change an underlying PR l, you need to rebase all of the dependent PRs.

There are tools that solve this problem! I work on one (Graphite), but there's also plenty of others like git-branchless and Sapling. All three of these are inspired by Facebook's internal fork of Mercurial (with Phabricator/"Diffs" for reviewing) -- Google has a similar model with Piper/Critique CLs, with Gerrit as the open source result.

So Facebook is still using Phabricator? Somehow I suspected that they had abandoned it since they seemingly stopped being involved in the open source Phabricator project.

There's a ton of cli tools to automate maintaining a stack of PR's, with new ones coming out all the time. I've seen 'spr' for a long time, and recently there's graphite's and even aviator came out with 'av'.

All supported by Reviewable, of course (sorry for the shameless plug!)
