So you've listed some important cons. I don't see the why outweighing those cons. If the why is "I really wanna play with this." then perhaps that outweighs the cons.
BTW on production servers we often don't do updates at all. That's because updates could break, beyond what's expected. Instead we apply updates on the base OS in a preproduction environment, then we build an image out of it, test it and send that image to the data centers where our production servers are. Test it some more in a staging environment. Then the update becomes - spin up new VMs in the production environment from the new image and destroy the old VMs.
