:speech_balloon: alexcrichton created PR review comment:

For this, can this be added to WasmFeatures unconditionally? That way rec-groups and such will all works as expected and it's just GC-bearing things that fail at runtime when gc is disabled at compile-time.

In theory GC_TYPES should be the only cnoditional-based-on-compile-time feature we need
