The chunking was introduced for just one purpose: To be able to detect rare

...really? All this is just to save a few cpu cycles in the rare cases of data
corruption that should have been handled by other layers (filesystem / 
transport
layer) in the first place? Why even bother?

No, it is more than that.  Imagine using OpenPGP to encrypt a full
filesystem to tape backup.  You necessarily want to be able to chunk
that as you are saving (and restoring).
