Regular oil changes, necessary or waste of money?

No. For long term storage drain off old stuff and fill the entire thing with whatever cheap oil you can get, even 30w mineral be fine as you won't run it, it is just a corrosion inhibitor.

So far, I've only ever changed oil on my race bikes once a year and that seems to be adequate really bearing in mind that a season is typically from late March to early October (less than 9 months at very low mileage). I was wondering if there really was an advantage in using brand new clean oil every time or if it was simply over-caution.

it is your call. you can send sample to lab and see how oil holds up.
