This of is not exactly the same as the empty string would become an array with one element.

@javiereguiluz only trusted_hosts and trusted_headers are impacted by that remark (as they don't perform a simple wrapping in array. Other changes in the PR are good.

@stof is right. I was reading the changes in my phone and didn’t realise that there were more changes.

Thanks for the review. I reverted the wrong changes.

Thank you @javiereguiluz.
