It seems the issue was not up to date, thanks for pointing it out (just commented in Github to make it clear for future readers).

Wasmer supports most of the Wasm-C-API, with some exceptions for APIs that are not that common to use: finalize, hostref and threads (tables just had some quirks on the implementation that we had to polish, but is generally implemented [1]).

If you are interested in running any of these cases using Wasmer via the Wasm-C-API please let us know... it should be mostly trivial to add support!
