I was working on a legacy CSJ project, and I tried to upgrade an OIDC library, but the newer version would only work with ESM. I decided to use that as an excuse to migrate our project to ESM. However, I hit a bug using dd-trace with ESM. Over a year later, that bug hasn't been resolved. I try to use ESM as much as possible for new projects, but it's not always simple to migrate existing projects to ESM.
