Previously, we've discussed giving lit a hybrid mode that would allow you to run all the tests w/o `REQUIRES: shell` in the internal shell, but still allow it to run all the shell tests if the shell is available. That would allow us to burn down the `REQUIRES: shell` bits over time, and figure out what features we want the internal shell to support.
