As demonstrated by CODETOOLS-7902598, getting the full classes list is expensive. Also, deopting one method after another would yield many safepoints. The only reason to favor individual deopts is to avoid deoptimizing Java compilers like Graal, where the cost of deopting the compiler itself is greater than the cost of deopting individual methods. For that, we would need to introduce an escape hatch. The probabilistic deopt serves little purpose as well: we need to be more deterministic and deopt before starting another test, not accept deopt in the middle of it.
