I can't imagine doing basic maintenace, ie: chain, tires, oil change, fork oil change, etc. without the centre stand. You would need another maintenance stand of some sort.
IMHO on a bike that weighs just around 500 lbs, wet, ready to ride, and a 150lb (or more) rider, the loss of 4 pounds, low on the bike, will NOT be noticable. OTOH, if you are setting up a track day or race bike, shedding every pound you can makes sense. Extra weight DOES impact acceleration and braking, but I just shed about 6 lbs with a new slip-on. I CANNOT tell the difference.
An old book by Gary Bailey explained that the average human can't notice a difference until it's in the 5-7% range. So you should be able to notice a reduction of 25-35 lbs.
