In an enterprise solution, you might have 10+ perspectives – some of which might have similar names – and without a clear description it will be confusing for a user (especially new users) to know which perspective is the correct one.
A better idea is to add a description/annotation property for each perspective where a more helpful text description can be provided indicating the business process, common types of analysis, etc. This would provide a metadata hook for self-service reporting tools (e.g. Excel, Power BI) as well as enterprise data cataloging solutions such as Azure Data Catalog.
Another helpful feature would be the ability to set the visibility of a perspective – or if you’re more familiar with the Tabular vernacular: “hide it from client tools”!
