I find the idea that I, sitting in my basement office, could hand-craft something nearly as powerful and maintainable as Spring Boot, as part of the project I'm actually working on, totally laughable. And the idea that this bespoke framework would somehow be more maintainable in five years is just lunacy. Even if Spring falls out of fashion, you'll still be able to find people that have a decent knowledge of Spring in five or ten years, just like you could find people who knew COBOL in the 90s. But how are you supposed to hire for "some guy that can figure out WTF this dude was doing when he wrote his own ORM a decade ago?"
