We have enabled the Generic.Arrays.ArrayIndent rule, which does some useful things, but also comes with the Generic.Arrays.ArrayIndent.CloseBraceNotNewLine rule which seems excessive. It forbids e.g. the following formatting:
$foo = [ 'data' => [ 'id' => 'Q123', ] ];
It also does strange things when auto "fixing" violations of the rule via phpcbf.
