  I guess I was hoping for a more informative answer. Are there at least categories of GCs, such that a VM could provide the n main GC types and most languages would be able to choose the appropriate ones? Or is GC very specific to each language?

    GCs have a lot of implementation specific quirks and properties, so for example a real-time app would be better served by shipping its own tested GC implementation than giving a "short pauses please" hint to the browser API.

      Given the dual needs, it might make sense to have different allocation schemes, one that uses the built-in GC, and which allows sharing/interop outside of WASM (JS, DOM, etc), and one which is entirely manual (or home-rolled GC), which does not (or makes you set a very specific set of flags which alerts the user). Without that, I'm not sure there's a way to really handle memory allocation and deallocation sanely that prevents most memory leaks.
