WARNING: MachineVision: remove from production T347972 needs to be done first
Once MachineVision has been undeployed from production this commit https://gerrit.wikimedia.org/r/plugins/gitiles/mediawiki/extensions/MachineVision/+/c4479e48f26080e5b60a49f62aba34f99f1c59bf ought to be reverted so that it can be used elsewhere
