Maybe I have just been neglecting my bike and I am an idiot(a distinct possibility!), but it certainly performs like near new condition after all those years.

I do see how a threadless set up is much lighter, that is fairly obvious.
Back when I had threaded headsets on mountain bikes, they used to come loose all the time, especially when used for rugged off-road riding. Fast, rocky downhills with rigid forks pounds the headset pretty hard. Suspension forks help since the force isn't driven directly to the headset.

15 years is way too long a maintainence interval for any bearing. Do it every year is probably a little bit of overkill but pick a happy median like 2 or 3 years. Your grease has probably polymerized by now and resembles teflon more than grease
