I personally think it should have slight give in it, I put my wheels back in every time I go to the track ( a lot ) and after after I've put my back wheel in I always lift the wheel off the ground and push on the pedals and let the wheel spin......to check to see how long it spins / resistance, if the chain is tight, it won't spin as long due to the fact that most chainrings aren't exactly circular, so you get "tight spots" ( I run dura ace chainring and sprocket by the way)....so a tight chain will most likely have more friction and less power transfer and will stress your components......cue everybody else telling me how perfectly circular their rings are!
