As above, true.
Personally, given the pain of swapping the oil pump while the engine is in the car should you have to later, and the consequences of an oil system vs. the cost of a new pump, it's certainly not a bad idea while you have the front cover off.
But, it really comes down to the existing pump. Is it reasonably new, or is it the original pump or of unknown origin? It's it original/unknown, I'd put in a new one just to feel better.
