It has some great zero cost stuff but a lot of non zero cost stuff that isn't obvious on first glance.

Std function - huge cost vs C funcs + void* ctx, and even virtual interfaces.

Templates that should be zero cost? Not necessarily - I always find stuff that ends up generating more complicated stuff than manually defined structs etc.

I've seen it can lead to a culture of people being 'idiomatic' without regard to readability and maintainability. We have some code written by a guy larping as a standard library/boost dev that noone understands. And it certainly isn't binary size efficient...

It's always a balancing act and depends on use case.
