moment has been in "maintenance mode" for a long time. In the docs and at the top of the README the project goes as far as to say "you should probably choose a different library".
It seems outdated for moment to still be listed as an "at-large" project without an asterix or alternative indicator to show that it's not really recommended to be used anymore.

*There is an increasing usage of moment (see below) despite the above facts. Any changes we can make to discourage it's usage I think are probably a good thing.
