Answer 1

The problem you are describing is expected behaviour and was changed in between versions.

Documentation from Laravel 5.4 Reference

The only method returns all of the key / value pairs that you request, even if the key is not present on the incoming request. When the key is not present on the request, the value will be null .

Documentation from Laravel 7.9 Reference

The only method returns all of the key / value pairs that you request; however, it will not return key / value pairs that are not present on the request.
