That's not part of ios, that is a library. I can't add that to someone else's app on the device. Apple should integrate it into iOS.
The user of the device should be able to compose apps, not only cooperating app writers.

I'm guessing you didn't even click on the web link, which, you will notice if you do, does not lead to any library. It's just a site (which I've never visited before this myself either... don't need to, to write or use inter-app URL launches) that hosts an informal registry of protocols along with information on what they launch.
