The man maintainers, at least from my own dealings with them, often don't like contributors. "Examples are nice, and I like your changes, but what if Paul Vixie doesn't?" It's easier to fork man completely and take it away from them, Xorg style.
You're free to try to incorporate these into the man pages. The creators of this (brilliant idea, btw, just what I have desired so many times in the past) are under no obligation to do so.
