I'm not sure if we should keep these and create them using just the latest guardian set

I think the real answer here is adding a typedMap implementation that is similar to constMap, but instead of using literal types, it should use the widened types. It could have exactly the same functionality as constMap only that its () operator throws when a lookup fails, while .get returns the widened type or undefined.

But that's ofc a bit larger of an undertaking.

Edit: There's also the issue that since constMap does all the type conversions, it figures out automagically whether a given mapping is bijective and hence uniquely invertible (like e.g. chain ids) or whether it isn't (like chain <> platform mapping) and can hence infer whether it needs to map to an array or not.
