I think it's intentional. The content of the chunks shouldn't be changed 
while being read. Let's say I implement #isCr: as

isCr: aCharacter

 	^$
 	== aCharacter

By default it will return true if the argument foo is a carriage return 
character, otherwise false. But if we allow changing the line endings in 
chunks, then its behavior might be different after loading.
