Can we please not make decisions about what code should be removed based 
on dodgy analogies? :)

Perhaps I missed something early on, but why are we proposing removing a 
function which (presumably) is stable and tested and works and is not 
broken? What maintenance is needed here?

Not so.

 >>> k = 'aaaa bbbb'
 >>> k.title()
'Aaaa Bbbb'
 >>> k[0].swapcase()+k[1:].lower()
'Aaaa bbbb'

"May" have problems?

pERSONNALLY, i THINK THAT A SWAPCASE COMMAND IS ESSENTIAL FOR TEXT 
EDITOR APPLICATIONS, TO AVOID THOSE LITTLE cAPS lOCK ACCIDENTS.
