What main benefit do sub-microflows offer?

Sub-microflows provide the main benefit of better maintainability. In Mendix, breaking down complex processes into smaller, more manageable sub-microflows simplifies the overall structure of the application. This modular approach allows developers to isolate specific tasks or logic within their microflows, making it easier to understand and modify individual components without affecting the entire system.

When changes need to be made, developers can focus on the relevant sub-microflow rather than navigating through a larger and more convoluted microflow. This can lead to reduced development time, fewer errors during updates, and improved collaboration among team members who can work on different sub-microflows simultaneously. Thus, the maintainability of the application is significantly enhanced, allowing for more efficient development practices and a more manageable codebase over time.
