Good upvote-worthy points, I'd just say that this is exactly the issue - eventually you end up with a Java++ implementation of exceptions.
As you say, the more limited implementation can be done more efficiently than the post post claims, but it has to be restricted and managed in a way that existing runtimes/compilers/languages haven't succeeded at so far... "just say no" earlier.
