Description: 

All candidates for constructor property promotion in Drupal core have been converted via rector.

For the vast majority of code, there should be no backwards compatibility break. However, if tests or similar code are manually constructing a class using named arguments, it may be necessary to update in the case that an argument has been changed from snake_case to camelCase.

Impacts: 
Site builders, administrators, editors
