Heya @frivoal, just a quick note to add that I’ve been working on 2 related PRs in the WCAG 2.x task force:

• Add new failure technique for non-semantic ruby annotation wcag#4829
• Modernize H62 to deprecate rb and complement new failure technique wcag#4830

I also made a quick test page to evaluate a screen reader experience in assorted tech combinations, with some additional comments in the PR.

The restoration of rb will certainly factor into both of these PRs, so I‘ll be watching this issue closely. 🙏🏻 If you have any insights you could share — particularly around the current Japanese assistive technology experience (PC-Talker, for example) — I’d be grateful.
