I didn't say all distros should be notified, for that exact reason. I listed a handful of major fistros.

Who gets to decide who the lucky few are?

Sounds like a job for the Linux Foundation maybe?

Human beings

Qualified by what?

Are you implying it requires expertise to figure out the ten (plus or minus a factor of two) biggest distros? I think most people that understand the context of the question can figure out pretty similar lists.
