The recently released Assignment Submission Celebration has garnered quite a bit of conversation over the last month. It's very obvious that they people of many different opinions about it. Everyone's opinion is probably correct for their situation which is why we need this to be a feature option. Something that individual schools, sub-accounts or even instructors can control for their classes. I'd even go a step further and say it would be good to have it as a per assignment option.
Currently it is an account level feature option but that is set to change in July. I would like to see it permanently remain an option for schools and teachers to decide to use or not.
