I don't consider that an improvement 🙈

Fine by me, but please fix the commit message ;)

Sure, opinions.
Mine is that moving from 40+ lines to 15 is more readable/maintainable and match perfectly...matches this usage, hence the PR (to be reviewed). 😄

What's wrong with the commit message? 🤔

Removed my assignment as this is php code style related which I would pass to @come-nc and @provokateurin for files backend

The commit type should be "refactoring" instead of "chore" https://github.com/angular/angular/blob/22b96b9/CONTRIBUTING.md#type.

lisbility => legibility or readability
