Not a spur at all, you are spot on! With higher orbits like GEO (35,000 km altitude) it actually makes more sense to take debris and dead satellites out even further to what is known as the 'graveyard' orbit. We can also see a future where we take parts off dead satellites (ie solar panels) and move them to a hub where they can be repurposed. On that note take a look at what the company Arkisys is doing!
