Love this- the read-only checkboxes are focusable, but cannot be checked/unchecked. 👍 I love that you added a bunch of the documentation from the guidelines site- thank you!
I did have a question about the expectations for what would be announced by a screenreader in read-only cases. Maybe that's something that's part of the research on read-only that's coming up. When using voice over, a read-only checkbox is announced like any of the other non-disabled checkboxes, so how would a user know that they cannot change the selection? I would think this would probably be a bigger discussion involving all of our team and some accessibility folks, so I'm not going to let it block my approval right now. Just wondered if you had any knowledge I don't!

Do you think we should eventually add a "read-only radio group" to the docs page? I was wondering why field group only has "read-only checkboxes" on this page, since read-only radios exist too.

That'd be a good idea for CSS-1005 that looks at this issue for radios.

Good call-out. VoiceOver reads it the same way that you had heard, for React Spectrum's version that uses |

This removes some unnecessary read-only styles. Read-only just needs to override disabled styles; otherwise it uses default styles (for both default and emphasized). Also adjusts template to include aria-disabled when in the read-only state, so screen readers such as VoiceOver do not announce the input as normal. Note that aria-readonly is not used as it is not announced property and MDN states that it is "not relevant" for input with type checkbox.
The previous display of the read-only state, without checkboxes and displaying commas did not match up with any guidelines. This update is to make the display of read-only match with what is implemented in React Spectrum. It also includes aria-labeledby in the template so the group is announced by screen readers.

For the input loop, consider checking one of them to be able to test for sure the immutability. Here's how I did it for the radio update as one option.
Description
As noted in CSS-833, the CSS, SWC, and RSP implementations of read-only checkboxes/checkbox groups, and the docs surrounding them, conflicted with each other. After discussing with the design team, it was decided that the first step would be for CSS to bring our visual styles in line with React's implementation.
Field group:
aria-labeledbyconnected to the group label, so this is announced as a group by the screen reader.Checkbox:
disabledattribute removed when read-only. Read-only still needs to be focusable / in the tab order.aria-disabled="true"when read-only, so screen readers do not announce as a normal interactive checkbox. For VoiceOver, this will add "dimmed" now and won't announce the shortcut to check or uncheck. Note that I've not usedaria-readonlylike as seen in React Spectrum as it is not announced by the screen reader (any differently than a normal checkbox) and MDN states that it is "not relevant" for input with type checkbox.This also updates all of the docs surrounding these things and adds a new storybook Docs example for Checkbox. The field group usage notes have been cleaned up as well.
