The conclusion/feedback from the OT was that we've shown that the WebAssembly Exceptions work well with the C++ toolchain that targets it, and that it had the desired impact (i.e. exception-using code is much smaller and faster). We targeted the OT to specific partners, and it enabled those partners to deploy to users and validate WebAssembly Exceptions based on their usage.
