The current behavior will crash any Bazel command immediately, due to our declared pip dependencies in WORKSPACE, if python3 can't be found. The new behavior will mock out these workspace dependencies and allow any non-python targets to run. Python targets will be skipped by wildcard expressions if there's no system python3, and will fail when run directly, due to compatibility mismatch.
