Typescript's --strict is sometimes a very different ballgame from default. I appreciate why in a brownfield you start with the default, but I don't understand how any project starts greenfield work without strict in 2025. (But also I've fought to get brownfield projects to --strict as fast as possible. Explicit `any` at least is code searchable with the most basic grep skills and gives you a TODO burndown chart for after the fastest conversion to --strict.)

Typescript's --strict still isn't technically Sound, in the functional programming sense, but that gets back to the pragmatism mentioned in the article of trying to get that 80/20 benefit of enough FP purity to reap as many benefits without insisting on the investment to get 100% purity. (Arguably why Typescript beat Flow in the marketplace.)
