In March 24, 2020 con call, the group decided to explore addition of Low vision friendly field in the user experience guide.
The User experience guide defines only high priority fields, while all accessibility metadata are available on another web page. Therefore, with the current arrangement advance users can make out from all accessibility metadata page, if a publication is low vision friendly or not. So, the check points for including this field in user experience guide are:

• Is it possible to extract accurate information for "Low vision friendly" from accessibility metadata (schema.org a11y metadata, ONIX a11y metadata etc.)
• The priority of Low vision friendly field, is it a sufficiently high priority field that should be added to fields to be displayed.
