I miss Gerrit from my last job. Stacked PRs on Github are horrible. Lots of problems stem from that: because stacked PRs are painful, people make large PRs, because the PRs are large, they take a long time to merge, because they take a long time to merge you need more rebases, needing more re-reviews etc.
