Actually, GEO sats start to drift quite quickly do to IIRC interaction with the Sun, Moon & Solar pressure.

It won't massively change the orbit (e.g. it won't either come down or escape to Solar orbit for tens of thousands of years), but in will change the orbit inclination quite a bit and also the period IIRC. And given how thin the usable GEO belt is (so that the GEOM comsat does not move from the ground PoV, it should be basically self cleaning - any dead sat or debris will quite quickly exit the thin GEO belt.

You might just need to watch for the cloud of stuff around it when maneuvering or if it ends up intersecting once in a while.
