Yes, I would do like that.

>Furthermore, if this is something beyond your control, you don't have other choice. If you can control the caller side, a better idea can be refactor this solution by introducing a parameter object, or maybe you already have an object with this data, and then you can pass it trough.

This can't be as this is the EXE entry parameters. This is launch from an icon.
