Why is this an issue?

Having unused properties adversely affects code readability, as their presence is confusing. Code that is never used should be removed to keep codebases clean and maintainable.

Exceptions

• Properties annotated with attributes, as these are often accessed via reflection.
• Properties with published visibility, as these are often accessed via reflection or used by the Delphi IDE for design-time configuration.

How to fix it

Remove the unused property.
