Yagni is a duality though (like a trinity, but two). You've just met Yagni's other face, You Are Going To Need It.

An important corollary to this is "0, 1, many".

Any time you are storing data, the acceptable number of items to handle are none, exactly one, or a number limited only by machine resources. Don't design a container to hold, say, up to 5 items.

On the other hand, instantiating/specializing a container to hold up to 5 items can be a perfectly reasonable thing to do, depending on the application. It might be a design requirement that a safety-critical program never has to restart due to heap fragmentation, for instance.

I don't understand. I would just about never want to use an unbounded buffer, for example, for a channel.

Yes but that is an artificial limit and not an architectural limitation. i.e. a feature added to code that was once / would have been infinite otherwise.
