I've had the misfortune of working professionally with CORBA, and I've spent some time trying to keep up with WIT/WASI/that whole situation. Whatever WIT is going to be, I can assure you it's very different from CORBA.

The best way I think to describe WIT is that it seems to be an attempt to design a new ABI, similar to the System V ABI but capable of representing the full set of typesystems found in every modern language. Then they want to use that ABI to define a bunch of POSIX-ish syscalls, and then have WebAssembly as the instruction set for their architecture-independent executable format.

The good news is that WIT/WASI/etc is an independent project from WebAssembly, so whether it succeeds or fails doesn't have much impact on the use of WebAssembly as a plugin mechanism.
