What are the disadvantages of passing entities through context in Go?

Passing entities through context in Go has several drawbacks:

• Context is intended for managing the lifetime and cancellation of operations, not for transmitting business data. Using it to pass entities violates its semantics.
• Lack of type safety: context stores values as interface{}, which requires type assertions and can lead to runtime errors.
• Increased coupling of code: entities passed through context become hidden dependencies, reducing readability and testability.
• Potential increase in the volume of transmitted data, which can negatively impact performance.

It is better to pass entities explicitly through function parameters, and use context only for managing cancellation, deadlines, and passing request-related metadata.
