That's true. Every system has some quantum of storage that must be handled as a unit, whether that is a logical block that can only be discarded entirely or whatever. But I think the relatively gigantic immutable extents discussed here are somewhat unusual.

I don't know the full picture behind their decision-making but immutability is much easier to reason about in a distributed system, in general.
