Its pretty much the norm in these parts when faced with an expensive rip out your dash to fix a leaking heater which you will never use here or just bypass the system.The choice is obvious. I've driven and done this myself to many cars really doesn't effect the engine cooling, a few feet of extra pipe can only provide so much more cooling, pretty negligible.
The same is done to the Range Rover L322 I drive but here the reason is the auxiliary heater cooling pump and its housing has literally turned to dust! LOLAnd I couldn't give a rats ass about spending $$$$$ to fix the heater, which I will never use here.
