I think its important to be careful on the scope. The ISO8601 spec is vast (I am implementing a new lib that implements the whole thing and its a huge task) .
> "I think we should probably consider this a bug, and fix functions which parse ISO-8601 dates so that they support what's allowed in the ISO-8601 spec". This is not a realistic goal for Elixir core I think. Ordinal dates, explicit and implicit forms of dates, century dates, decade dates, ..... thats a lot of surface area for maintenance that in the spirit of Elixir probably lies better in an external library if required.
