`"strict": true` is turned on by default when you run `tsc --init` and is recommended in every talk by everyone, including the TypeScript team... So I'm afraid the defaults are indeed sane and exactly what you want. I'm not sure much of what you've said in these threads really gels with reality so far. For anyone confused: `"strict": true` in `tsconfig.json` just blanket enables all type checks, including future ones. You can then opt out of specific ones of your choosing if there's too much pain caused by the original authors, but none of those things are added by default. The TS team wants you to leave strict mode on.
