There's a cultural problem in the TypeScript ecosystem, I find, where people are impressed (with both themselves and others) when complex interfaces can be expressed in the type system, and tend to embrace that instead of settling for simpler (and often admittedly more verbose) ones. Maybe that's because they're an ex-JS programmer who wants to use the exact same interface they'd use in JS with no compromise, or maybe it's just because they think it's cool. Either way I think it's really detrimental to TypeScript as a whole.
