Using more and more constructor property promotion with PHP 8.0 now, I more often end up having empty contructor bodies and the current ruleset requires to always have the opening and closing curly braces in new lines.

Might be personal preference which just triggers me a lot, but my suggestion would be to switch on the single_line_empty_body rule to allow for a more compact way of writing this

Empty body of class, interface, trait, enum or function must be abbreviated as {} and placed on the same line as the previous symbol, separated by a single space.

Before

class MyService {
	public function __construct(
		private IURLGenerator $urlGenerator,
	) {
	}
}

After

class MyService {
	public function __construct(
		private IURLGenerator $urlGenerator,
	) {}
}
