Goal

I'd like to define global dependencies from inside the packages like this:

packages/testrec/turbo.json

{
    "$schema": "https://turborepo.org/schema.json",
    "extends": [
        "//"
    ],
    "pipeline": {
        "build": {
            "dependedBy": [
                "test"
            ]
        }
    },
}

This would result in any test task, regardless of the dependency graph, requiring this package to run its build script before any test task can run.

Now, I'm aware that this can be defined on the top level turbo.json file like this:

turbo.json

{
    "$schema": "https://turborepo.org/schema.json",
    "pipeline": {
        "test": {
            "dependsOn": [
                "testrec#build"
            ],
            "outputMode": "new-only"
        }
    }
}

Why?

This however couples this turbo.json to this specific project, and having a bunch of projects, I'd like to have a single turbo.json that I can copy into all of them.

Some projects have unique dependencies, outside of the dependency tree.

Workaround

I can define a turbo.json file in every package to define this unique dependency

packages/*/turbo.json

{
    "$schema": "https://turborepo.org/schema.json",
    "extends": [
        "//"
    ],
    "pipeline": {
        "test": {
            "dependsOn": [
                "^build",
                "testrec#build"
            ]
        }
    }
}

But this means I have to put this in every package, better than nothing, but kinda ugly. And I can forget it when creating a new package.
