Is label sorting necessary?

I want to use `Superrecord` to work with foreign data.
I need records `Rec '["foo" := Int, "bar" := Float]` and `Rec '["bar" := Float, "foo" := Int]` to be different, because they correspond to different C structs, but I can't even create `Rec '["foo" := Int, "bar" := Float]` because `rcons` sorts labels of its result record.

So, why do you need label sorting? Can the library work without it?
