alexcrichton opened PR #6692 from alexcrichton:smaller-unsafe-scope to bytecodealliance:main:

This commit fixes a mistake in the PrePatchedFuncRef type where it has an unsafe impl to make it send/sync but the target of the impl was mistakenly InstancePre<T>

Note that this doesn't actually have any impact on the send/sync-ness of InstancePre<T> since it's not storing an instance of T, so it's always Send/Sync anyway. Nevertheless this reduces the scope of unsafety slightly as was originally intended.

This makes sense. But since this was passing CI before, I guess that nothing was depending on PrePatchedFuncRef being Send or Sync, so do we need those at all? Could these unsafe impls just be deleted instead?
