RadioGroup's label prop as a ReactNode will wrap its own Label element

[cyu06]

After #4276 allowed label to be a ReactNode, I would've expected that I could pass in my own Label element rather than getting forced to get a wrapped one

blueprint/packages/core/src/components/forms/radioGroup.tsx

Line 81 in 1505703

{label == null ? null : <label className={Classes.LABEL}>{label}</label>}

Well I guess that would've been a slight runtime break if we removed the wrapping label, since #4276 was just a type change. Can you describe your use case a bit more? Why do you need to customize the label?
