Idea: Pro Form submission: Data retention

Currently, Pro Form gives the possibility to set a maximum number of submissions to be stored. This is good, but not sufficient, since this does not allow to set a time for data retention. This would ease compliance to set a time length for which records are kept. For instance, keep the submissions for x years/months/days, so that after that time, the submission stored is deleted.

What do you think about this idea?
