I wish they (and all repo caretakers) would do this more often. Each comment notifies every person who subscribes to an issue, and if that comment adds nothing other than an information-free expression of feels that no-one other than the feeler is interested in, that notification is spam. Every moronic "+1" or "any update on this issue" or "outrageous!" could spam thousands of people.

I've had to unsubscribe from many issues I'd like to follow because of spam caused by information-free comments.
