I am excited by the prospect of booting Wasm binaries without any JS glue, but when I've looked at the documentation for the component model and WIT it says that resources are references passed using a borrow checking model. That would be a serious downgrade compared to the GC-managed reference passing I can do today with Wasm GC. Do you know if there are any plans to resolve this mismatch?

Relevant: https://github.com/WebAssembly/component-model/issues/525

In my experience people are often disappointed by the shared-nothing architecture of the component model. I guess that shared-nothing architecture makes it impossible to properly share GC objects across component boundaries. But they can still be shared across core module boundaries.

A lot of the time I think you just won’t want to use multiple components. It’s nice to be able to compose them together, I guess, but in general it seems to me that a toolchain will typically just want to generate a single big component so that everything can interact without limits internally.

The tooling has been in it's early days for a long time. As quickly as that can improve, so will the uptake. The technology itself is quite capable.

What do you mean by churn in this context?
