This is technical jargon primarily used in software development and programming communities in both Brazil and the USA. It reflects concerns about code quality, maintainability, and system architecture that are central to modern software engineering practices. The term became more prominent with the rise of microservices, containerization, and dependency management tools. In Brazilian tech communities, especially in São Paulo's startup scene, both 'dependência oculta' and 'dependência implícita' are used interchangeably.
