alexcrichton opened PR #4215 from component-vmcomponent to main:

This commit fills out the wasmtime-runtime crate's support for
VMComponentContext and creates it as part of the instantiation
process. This moves a few maps that were temporarily allocated in an
InstanceData into the VMComponentContext and additionally reads the
canonical options data from there instead.

This type still won't be used in its "full glory" until the lowering of
host functions is completely implemented, however, which will be coming
in a future commit.

This isn't technically safe right? Since the ComponentInstance is logically pinned, giving out an &mut would allow moving it out by std::mem::replaceing it.

That's a great point actually and something I totally missed! I removed this, made it a private internal accessor, and reexported &mut self methods from the un-owned version to the owned version.
