The only benefit you would get is the ability to request updates. I work closely with the team that would answer the case and they have the same abilities that I do. They would need the reproduction as well and depending on the route cause either create a PIT with a bug report for you to monitor or give you advice on how to get it to work. Ultimately it's your call but either way having a repro project would be needed.
Just note there is no guarantee on bug fixes.
