For https://gerrit.wikimedia.org/r/#/c/300755/
"justinrainbow/json-schema": "~1.6",
And 1.6.1 is in the committed vendor repo, we get a rather stupid error message
15:52:38 justinrainbow/json-schema: 1.6.1 installed, ~1.6 required. 15:52:38 Error: your composer.lock file is not up to date. Run "composer update" to install newer dependencies
Or is this intentional? I know various extensions use ~ syntax...
