Description
One goal I've heard is that descriptor structs can be eventually implemented directly using the existing Shape/Map/Structure objects that Web VMs already use on wasm GC objects.
However, a Shape (in SM at least) is not a JS object and should not be accessible to JS scripts. I don't think it could conceivably work even as an opaque thing like wasm GC objects are now. Things like typeof wouldn't know what to do with it.

Research direction
Start by reviewing the existing Shape/Map/Structure objects in Web VMs and the current ToJSValue behavior for wasm GC objects. Determine whether descriptor structs can be exposed without making internal shapes accessible to scripts, including defined behavior for typeof; done means a documented decision on their allowed representation and JavaScript observability.
