general compliment for F19/F20

[Haïkel Guémar]

I'm also dogfooding Fedora for almost a decade and i always had 
updates-testing enabled since it exists.
There were times when Fedora was very aggressive on updates and it had 
an impact (a positive one overall, i hope)

There are two poles in our community: one wishing a more bleeding 
approach, the other emphasizes on stability.
We can't please everyone, but having different products over a common 
base might concile these two sides
