I am the same to an extent, I like to have at least 2 things to be doing in a zone to stop me getting bored but came to the same conclusions you did about putting it in the guide
I think how much you like to multi task varies from person to person so I decided to not to outright recommend it, it's not really as big an issue low level anyway and by the time it is people should have an idea of how they like to do things.
