Registered Metatags at WHATWG

Hello, 
I registered two Meta-Tags at WHATWG Wiki and found a Metatag, which are not included in W3 Validator:

bitcoin Used for bitcoin adress
startver Used to verify WebApps for JokeNetwork's Start!-WebApp
blazerr-support-identifier Used to identify users for JokeNetwork's Blazerr Support-System

Thank you very much,
