This is probably true for those who are more experienced - once you 'get' lifetimes and accrue code the cost of compiling is going to go up and the cost of understanding Rust goes down. For newcomers it's the opposite. They'll have tiny projects, maybe in the hundreds-of-lines range, probably not a ton of fancy types and generics either. Their compile times are going to be quite small. But lifetimes, those will cost them a ton.
