Very unlikely to happen.
Accessibility support is lacking in Linux distribution generally so a small project like Whonix can’t fix it.
Generates lots of technical complications. Many accessibility depending users require voice input/output. Technically requires phonon. Which then due to dependencies requires VLC to be installed on Whonix-Gateway, see ticket:
https://phabricator.whonix.org/T786
Accessibility support is like starting a new project. Rather, I’d defer this to:
- Qubes - better accessibility support - install accessibility tools by default in dom0 and templates · Issue #1596 · QubesOS/qubes-issues · GitHub
- better accessibility support in Debian
- a yet to be invented Linux distribution, based on Debian, focused on being deployed in VMs such as VirtualBox and accessibility
Other issues:
- very low demand
- very hard to find users who care and who can give feedback
- accessibility tools could be automatically removed / you probably should remove them
