Good point. I'm not sure why this happens. I think this behavior is 
dictated by the respective format's prepare(), valid() and split() so 
it's not something a core change would fix.

I know I and JimF have identified and discussed the need for being 
promiscuos when reading john.pot (eg. accept bare hashes or deprecated 
tags), and strict when writing to it. This is something we could add to 
the Test Suite.
