This was requested by a team member who would like for some tests to remain invokable (in thier own $HOME) directly via littlecheck without relying on the test driver to prep the environment. A comment explaining the rationale is also added so this doesn't get passed down as folklore "you need to include this for tests to run" even though no one understands why.
