Since the option isearch-lazy-highlight-cleanup exists I extend my 
suggestion a bit to let C-RET (or S-RET) mean "toggle 
isearch-lazy-highlight-cleanup for me temporary when I exit search".

That way there is less to keep in your head when you exit isearch. You 
do not have to remember if you already have toggled the option because 
it is always in its usual state. You would have to do that if you 
toggled the option during the search and that would distract your brain 
I guess which is working with how to search at that moment.
