Well done on a great post!
I for one, am for it. For me, there should always be transparency.
It takes hard work to build a community, and if I must see it "disappear" after I've worked so hard on it, I will be heartbroken.

In fact, there should be an approval process for communities, just like the Achievement 1 post, and the Steemit team will then create the community and share keys.
