There’s two fundamental issues with that sort of approach: 1st, is the deltaV difference between useful and desirable orbits that satellite operators want to be in and the selected “disposal orbit band”… with GEO it’s just a small deltaV Hohmann transfer “up” into the geo graveyard “band”… the graveyard starts just 300km further out from earth and the geostationary satellite typically use on the order of 11m/s… which is bugger all. The Manned Manoeuvring Unit “EVA jetpack” had approximately 25m/s. 2nd, is sometimes overlooked, but nonetheless quite important aspect. Any graveyard orbit intended for use by multiple objects should cross the orbits of as few active spacecraft as possible and have as low of a relative velocity between the objects in that graveyard orbit as possible… Geosynchronous satellites are basically above all but a small number of very specific satellites in places like lunar orbit or Lagrange points, and “in a ring” so, performing a gentle boost to the graveyard orbit gets them out of the way of almost everything and they are at least as far as satellites go, not moving particularly fast relative to each other, and they are so high up nothing else is going to regularly cross their obit, so it’s a relatively low risk environment for a satellite on satellite collision… the majority of cycling orbits tend to have a LOT of relative velocity compared to the orbits they cross, tangential crossings leave high relative velocity, and the elongated orbits tend to end up crossing through a lot of space as the orbital precession moves along… on top of that the deltaV to go from most orbits to a cycling orbit tends to be relatively high, not as much as a full transfer to lunar orbit, but it’s basically in the same ballpark as using the moon to kick yourself into a solar orbit, which while potentially doable at considerable extra cost for a GEO satellite, is completely impossible for the sort of smaller LEO and MEO satellites without an entire kick stage, tug or other propulsion which would at least for LEO probably weigh more than the satellite does.
