Based on the rarity of questions about notifications, I suspect that you could count the number of people who use them on one hand. If they are as rarely used as I suspect, I wonder if it makes sense to add yet another variant that is likely to be used by a single person? Perhaps it would be possible to collapse the entire notifications service into a data-driven class that could send arbitrary messages to arbitrary endpoints?
