Early developer preview: Retweeting API

This stems from a misreading of why people retweet stuff. People retweet stuff because someone else said something they'd like to say themselves. Adding the RT: @source is a concession to good manners and etiquette. If every retweet someone sends is marked as "unoriginal content" I can see the number of things retweeted in general take a nosedive. Who wants to be exposed as a conduit for other people's ideas?
Are you giving your own opinion on the matter or is this something mentioned by the Twitter Dev team?
This would not be a bad thing.
Not to go on a rant but working with the Twitter API restore sanity I lost back when I worked with Facebook's "thing". I don't even want to call it an API, whatever it was.
