Wheels are built so as to have equal tension in the spokes, thus the tension in the wheel should be in equalibrium, with that said, wheels also flex, which does depend on components like rim construction, spoke type, i.e. plain gauge (constant amount of material, low elastisity, generally requiring more tweeking and maintenance) or double/triple butted (less material, higher elastisity, requiring less tweeking, etc.....), but providing the amount of flex doesn't exceed the amount of tension already in the wheel then it should spring back to its original position. So, maybe there's noting to worry about, except that your spokes may require that extra bit of tension. Some people in the road bike scene like to soft spoke there wheels, good if you're a light weight rider, however if you're 266lb, then you need well-strong burly wheels, which as 'new_dharma' said "OE rims are cheap", and can have a tendency to taco. It is often said that after the bike frame the wheels are the most important component.
