In my opinion it still lacks more automatic deploy mechanisms. Ansible has some great ideas, but I guess the time to write your deploy scripts is needed. I'm still hoping for a salt package like system. (
https://github.com/saltstack-formulas) Where you only use your top.sls and perhaps some custom pillar data, to define how packages interact or where packages are needed.
Define wordpress running on 2 appservers + 1 database node + 1 loadbalancer with ssl termination and export db and pipe it through gpg via this pillar key. etc. pp
