Previously, there was no formalization of property naming; only loose conventions were followed.
While these conventions served relatively well in practice, they created gaps, resulting in a loss of uniformity in some cases and leaving friction in the process of naming new properties.

### Terminology

**Public properties** are formally a part of the Public API.
Public properties are **stable properties**: they CANNOT be renamed or removed without notice.
