Comment 11 for bug 1198465

To be clear about my settings suggestion, I don't think we're losing any flexibility. Of course, I might be misunderstanding something fundamental, so please correct me if needed :)

If we keep:

bill.prohibit_negative_balance_default
bill.prohibit_negative_balance_on_lost
bill.negative_balance_interval_default
bill.negative_balance_interval_on_lost

Ideally, under most scenarios, we only need to set one setting, the "default" setting. This treats lost and overdue the same. On the other hand, if we need lost and overdue treated differently, we set the "default" one way and "lost" the other way (as appropriate for our needs).

I do think it is best to keep the "default" to preserve the "set one setting" behavior.
