Being in active development does not mean it’s not ready. To recognize faults or things that can be improved upon and keeping track of those does not mean it’s not ready.
By your definition, not a single distro is ready. Which, to be frank, is a perfectly fine stance to hold if the extent of this is explored and explained. However, you pose it as if Fedora Atomic is the one with that problem (implying others don’t have that issue), which is just plain false.
