This means we can use it in the next commit. Also, it was surprising
for the function to be returning a tuple of values, instead of just
the service object. Since the consumers of the function only needed
the user as auditing data, it's fine to use the first team member.
this means that on non-prod envs, it reflects that environment.
it needs to be a lamdba, because the column object is created at import
time, when current_app.config won't have been loaded - this means that
when you create a Service object, that lambda executes and grabs the
correct default value
