> GEO is very cramped. It's just a circle, not a sphere.

"cramped" the way that like, Alaska is cramped on account of how everybody has to live on the surface, not evenly distributed through the volume of the planet?

Like yeah, it's "just a circle" but did you check the radius of that circle?

Remember if there's debris, the debris isn't stuck in the circle, but, any time it's not in the circle it's harmless. This has the effect of significantly defusing the problem, so in total it's too low risk to be worth considering.
