My guess is that the performance overhead of inserting it into wasm was judged unacceptable. It's a little odd to me, I was surprised when I discovered I couldn't realistically pause a tab running wasm benchmarks - often when I try to close the chrome tab it just hangs. The runtime I work on (.NET) inserts safepoints at back branches in some cases specifically to enable pausing for GC. It wouldn't surprise me if using WASM GC would cause the runtime to start inserting safepoints as well.
