Though I mostly use pnpm these days, yarn still has a feature that I frequently miss: the project-local cache[0]. Basically, every dependency archive fetched from a registry is stored in your repo in .yarn/cache, so unless you're adding/updating dependencies a `yarn install` will work fully offline.

I'm sure there are drawbacks to this method regarding repo size etc., but it just feels good knowing that my repo contains everything needed to install and run any version of my project.

I should add: this is enabled by adding `enableGlobalCache: false` to .yarnrc.yml, though I think it was the default for a bit when Yarn 2 first released.
