Is it possible to disable garbage collection entirely when compiling for WASI?

Kotlin compiler has no GC configuration. Some runtimes could have an option to to disable GC when it is implemented. For example, proposed <https://github.com/bytecodealliance/rfcs/blob/main/accepted/wasm-gc.md#the-null-gc|wasmtime Null GC>.

Thanks for the answer, let's hope that Wasmtime's GC implementation progresses quickly!

Short-lived programs could finish before requiring a GC. Longer-lived programs need to be careful to limit allocations. An extreme example would be allocating all the necessary memory upfront and never allocating again.
