It's very useful for multiple scenarios: 1. Learning new syntax. E.g. the new switch expressions are pretty neat and better than the old switch statements. Changing and learning how to write them is super easy thanks to this feature.

2. A code base with less then good practices is vastly easier to adjust to better standards than in python. I've done both and dotnet is mostly applying suggestions and then looking for more advanced problems which where not caught by automatic analysis. It's not perfect, but it reduces useless churn.

This also holds true for rider and vs with resharper.
