Comment 12 for bug 1668532

This solution is neither acceptable nor desirable, at least for the following reasons:

 * Docker is still being actively used in 9.x for cloud validation
 * It hasn't been properly deprecated with a wide announcement in 8.0
 * There is a probability that it's needed for 3rd-party tools
 * It doesn't fit the Maintenance Policy (functional changes not fixing issues are prohibited)

Keeping in mind all the above and that disadvantages of the docker removal outweigh its possible advantages, I'm going to close this report as Won't Fix in the 9.x series.
