Personally, the status level caps are the main reason I literally never invest any points into learning any other status removal skill. I've lost track of the number of times I've run afowl of Barghest poison I couldn't cure, for example.

I'd argue Cleanse Body is too good, yes, but not for the lack of level caps, but for how many status are affected by it. I personally don't see how half the statuses it affects are "cleansing your body" as Fear is a psychological thing, rather than a physical one. Immobilize is caused by external forces; outside of maybe Stone Gaze, no immobilize effect is ever anything other than your legs being pinned via an external force (Roots, Grass, Corpse Hands, you get the idea.)

Personally? I'd leave the poison/burn removal without caps, but just remove all the other effects. To still keep it as a sink for 5 SP, it could cure only Burn at rank 1, adding Poison at rank 3, and getting -2 to the FP cost per rank, with rank 5 costing what it currently costs.
