It turns out one of our engineers was already working on notification on renewal, it just didn't make the first release because we were rushing to get changes out to allow as many customers as possible to renew before expiration.
The second suggestion you make is a fair amount of work. Also, we wouldn't be able to say in all cases when it would be possible to fill every delegation. And it's not clear if the situation is likely to repeat in the future. But if it appears likely, we'll consider it.
it seems like your engineers know how to do their jobs perfectly...
however
can you tell me what's this invalid memo is about...
