@matallo what is stopping you from adding RangeSlider to magic-ui and doing a CSS override? Does this need to be in Polaris ASAP? Are 3P app developers going to need these features?

@alex-page, the same prop got added to several Polaris components already, including TextField, Checkbox, RadioButton, Select and ChoiceList.

At the moment I don't think 3P app developers are going to need this feature. In general, do we consider it a bad practice to add a prop to Polaris for something that's required in the admin, but not for 3P app developers?

That can be a solution, we're doing something similar for RichTextEditor. As @mathildebuenerd mentioned I'm following the same pattern as prior components with tone="magic" but there's a wider discussion to be had.

Does this need to be in Polaris ASAP? Are 3P app developers going to need these features?

I don't think so immediately, but I'll let the team using this to answer. Currently the feature is behind a beta flag for the Admin if I'm not wrong.
