Consider making Weather's daily t-shirt notifications a separate service
Roger brings up some more radical thoughts on the Weather rewrite. Trying to paraphrase what he said:
The current weather service is actually two services: a subscription service that sends email when a relay goes away, and a notification service that sends email to any relay operator who has qualified for a t-shirt. The latter service is unique and important for the Tor network, whereas the former service could be done in other ways, like a munin or something. If we fix the t-shirt service, Roger would care a great deal less about the subscription service being discontinued.
We should find out how many people use the subscription service before deciding something here. See #10699 (moved).
Even if we decide to split up Weather, we should still consider fixing the subscription part. But our priority may shift to fixing the t-shirt part first.
