PNPM Compatibility DB | Rush

Both Yarn and PNPM support a feature called the Compatibility DB, which is a public database of package.json fixups. These fixups solve known issues that the official maintainer of an NPM package may be unwilling to solve. (The best practice would be to avoid such packages, but often that is impractical.) Compatibility DB fixups are similar to user-authored rules found in .pnpmfile.cjs. They are maintained with the @yarnpkg/extensions package.
