There may be a similar legibility point about severity levels. Some boss somewhere has to put the set of tasks in priority order for the development team, and once it's in that order, severity levels are useless for the developers. But they might be useful as a way for the person submitting the issue to communicate something to the boss who does the ordering. Say there's a billing system. One of the accounts receivable clerks notices that due dates aren't properly adjusted for public holidays. As a developer, do you know how big a deal that is? Probably not. Doesn't sound like a big deal. But maybe it means we're imposing penalty charges on customers where we shouldn't be, and that's a huge legal and reputational risk. Or maybe it really isn't a big deal! The boss will need to have a conversation with the clerk to learn all this, but maybe having a severity field is an ice-breaker for that conversation.
