Shall we use `#!/usr/bin/env python3` for newer utility scripts?

I know https://llvm.org/docs/GettingStarted.html#software specifies `>=2.7` (presumably Python 2) and some infrastructure rely on Python 2. But these utility scripts are independent and can be migrated to Python 3. https://pythonclock.org/
