I have to admit my use of Docker is quite a bit different than yours and while I definitely understand the concerns / complaints if they aren't using it can we really be made if there are changes like this?
I only use Docker on AWS Elastic Beanstalk and they only update for security issues most often (Beanstalk is using 1.6 as I type this).
If I recall even the config file format changes between 1.6 and 1.7
