After some online searching, it seems that JAWS at least used to support IAccessible2, originally mainly for IBM Lotus Symphony. According to a tweet by Marco Zehe from December last year, JAWS handles Chromium and Edge via IAccessible2. (See https://twitter.com/MarcoInEnglish/status/1471523578805997570 )
That sounds promising, JAWS was what I vaguely had in mind about having been mentioned of presumably not supporting IAccessible2 (well) in the past.
Twitter is not an ideal source, but I couldn't find any documentation related to IAccessible2 on Freedom Scientific's website. They do have documentation on to use script access to UIAutomation: https://support.freedomscientific.com/support/jawsdocumentation/UIAScriptAPI but nothing similar for IAccessible2. This calls for some LibreOffice testing with JAWS; I hope to do some of that next weekend.
