Yes you should delete. There is no practical reason to send messages  
in anything else but UTF-8 these days.  Sending messages in any other  
charset risks losing information/characters in the sent message.

Having said the above, I am going to go back and add an upgrade task  
to 5.0 that deletes the current value of sending_charset.
