nx: Unable to remove dependencies between projects as specified in the docs via `implicitDependencies`

Current Behavior

In https://nx.dev/l/r/core-concepts/configuration, it specified that we can remove dependencies between projects (e.g. a lib seems to build an app while it does not have a connection via the project graph, so I’d like to explicitly remove it)

Finally, you can remove dependencies between projects. The following say even though the project imports 'mylib', it's not a dependency Nx should be concerned with.

{
  //... other project config
  "tags": [],
  "implicitDependencies": ["!mylib"]
}

When adding "implicitDependencies": ["!mylib"] project.json file of a lib, then trying to build it, I get:

>  NX   ERROR  Configuration Error

  The following implicitDependencies specified in project configurations are invalid:
      lib
          !mylib

From what I can see, support for this functionality isn’t anywhere in the relevant areas of nx.

Expected Behavior

Should build the library without building mylib.
