Exactly. Like all ideological arguments it completely ignores actual real-world evidence. Somebody should sit down and analyze real codebases and understand and quantify how much these projects would be improved by real generics and proper exception handling. My (anecdotal) experience and speculation suggests that you'd see massive reduction in complexity and lines of code (especially when you consider code-gen).

But then this is part of a larger problem of the community which isn't motivated by evidence or basic pragmatism but rather strict adherence to a philosophy.
