FWIW, the no-model-argument-in-route-templates came out of the Octane migration for the app I work on, and we do not believe it should be a recommended rule. It is a useful tool to have to work around that bug, but @model is absolutely what we should be going with in general (and certainly all new code should be authored that way). The only time you want that lint is when you’re migrating Classic code and trying to exactly preserve Classic behavior.
