It invites a nonsense usage (i.e. running "make test" under that
environment variable setting); that is not a good trade-off.

The existing tests are designed to be black-box tests, not function
level unit tests, and touching lower level code carelessly affects
other parts of the system you did not know the interactions about.
What does "TDD case" change anything in that equation?
