FWIW I think that the concurrent code is going to need some relatively invasive changes to handle the GC ABI. Not only because of rooting everywhere but also because limits/maximums in params/results are pretty heavily baked in to the implementation on the host side. It might be best to just reject this for now and have a separate todo! or component-model-async integration being a big TODO item.

For example there's code like this which is definitely not correct for GC.
