I can see -filein being useful for a production patch use-case, but the rest of those go back to mixing the Smalltalk environment in with the operating-system environment.  For safe and scalable headless interaction, you would just use a server.  I never knew if there was an actual use-case for -evaluate and -cli other than novelty.  Is there?

Both are useful for testing. —evaluate is useful in eg a (unix software build style) configure context.  —cli is useful for people who want to explore, learn, demo, etc.  

But since they don’t really cost much why are you bothering to try and veto them?
