That method allows accessing the var handle cache on a ValueLayout, but the overload would always have to create a new VarHandle with the bound coordinate (unless we want a specialized cache for `0` offset maybe...). So, I don't think having on overload there is super important.

Good point. As you mention, that overload would have to spin a new MH (unless we add another cached stable field somewhere - but that would have to special case `0L` somehow). So, I think the current combination of overloads is fine.
