I don't know if this is a good example, but if you look at StackOverflow,
it seems that people who want to see a list of constraints appear regularly.
(The other day, I also wanted to see the list, and I arrived at this site)
Therefore, the only thing that hasn't been implemented so far is that no one
could communicate the request to -hackers, and I think there is demand.
