As a developer it is worth it as long as you have separate teams responsible for development and production. Segmentation means that a prod server can't accidentally be configured to access a dev resource (db instance, etc). If you have development hand off installation packages and instructions it also means that dev never has to touch prod servers (except read access to logs, etc). It also eliminates the temptation to "temporarily" use a dev machine/instance as part of prod to solve a problem (and then leaving it that way for years).
