> Unsatisfying workarounds [...] Use linear memory for bytevectors
It never makes sense to use GC for leaf memory if you're in a language that offers both, since mere refcounting (or a GC'ed object containing a unique pointer) is trivial to implement.
There are a lot of languages where it's expensive to make the mistake this post is making. (I don't know much about WASM in particular; it may still have other errors).
Sorry but it's just a different choice not a mistake. I do realtime graphics just fine in non-web managed memory languages.
