If contracts have examples, use them when mocking

[ScotterC]

At the moment, mocks are populated by code within the mock/ directory. If a contract has examples in it, they may have properties that are important for developer requesting them. For instance, showcasing a prototype to a client where you want to determine the dummy data.

My suggestion would be to have a config option that checks for using examples from contracts first before falling back to automatic mock data.
