While I think this was a decent idea, in actual practice there are too many possibilities / permutations of quoting etc that can potentially result in a false positive and prevent the user from executing their container. Net result is that the security routine would have to be continually updated as more legit usages com to light.
Since the whole point of the original change was to prevent repository maintainers from maliciously executing arbitrary commands in the docker run and not to impact end-users at all, this will have to be purely enforced on CA's end instead.
