witx: remove supertypes from the handle type#358
Merged
Conversation
the idea here was to enable handles to have a subtyping hierarchy, but this isnt compatible with wasm extern refs and we never used it anywhere, so its safe to delete all this code.

The subtype relationships are meant to anticipate subtyping in type imports. Type imports are better than externref for WASI because externrefs aren't virtualizable, since they can only be created by the host, so it'd be good to keep the subtype relationships in anticipation of using them with type imports. |

oh! as usual I got it backwards. I think i'd like to keep this code out for YAGNI reasons. If we need to add it back in, its not too difficult to do so, either by revert or manually. |
