I'm not a SDK dev but I'm the author of 2 apps with QR code scanning support 
so I might be able to give some insight.

In my humble opinion, this is not critical enough to be addressed in the SDK 
anytime soon given the other open work packages and issues there are still 
around. However, feel free to reuse the code from Tagger and/or Authenticator. 
It's quite simple, you just need to copy the classes you need and package them 
up in a plugin (or register it through main.cpp).

Feel free to ping me in IRC for assistance if you run into troubles.

Hope that helps,
Michael
