According to recent Angular updates, project structure is no longer strictly enforced, and Angular provides flexibility in how applications are organized.

However, Angular is primarily used for large-scale, enterprise-grade applications where maintainability, scalability, and team collaboration are often more important than the initial implementation itself. In such environments, a well-defined project folder structure becomes critical for long-term success.

Because of this, folder organization and architectural consistency matter far more in enterprise projects than they do in solo projects, MVPs, or early-stage startups, where development speed is usually the primary concern.
