I think the main answer here is "it depends".
If you are putting a group like retail only transactions [e.g office supplies, facilities accounts, etc.], then I would say probably not.
There isn't much data exchange there, and the risk is infinitesimal.
If you are setting up groups like municipalities or federal/government agencies that are something you have to work with, then I would say creating a base account that doesn't need attention might be a better path.
The real bottom line with this is to follow what your policy says. If it's not clear, then make the choice of a direction, and do it.
If you work with auditors, they will probably let you know if there is a best practice that they recommend, if it differs from your policy.
