Make Core Text Renderer Accessible in VoiceOver

Is your feature request about something that is currently impossible or hard to do? Please describe the problem.

Under the Advanced menu in settings for the checkbox Use Core Text renderer appears the message:

(Deprecated) Deselect this option to use the legacy renderer, which is unsupported and will be removed in a future version.

However, at present, the Core Text renderer is not accessible in VoiceOver.

Describe the solution you'd like

Make Core Text renderer accessible in VoiceOver prior to the removal of the legacy renderer.

Describe alternatives you've considered

If the legacy renderer is removed prior to making Core Text accessible then I won't be able to use MacVim anymore as a blind user. And MacVim is great, so this would be a sad day indeed.

I'd have to use gasp emacs? Or use vim in a terminal full time? Yuck.

「Use Core Text renderer」と表示されたAdvanced settingsのチェックボックスから始め、Core Text rendererが選択されているときのVoiceOverでの動作と比較してください。Core Text rendererがlegacy rendererを削除する前にVoiceOverで使用可能になれば、作業は完了です。
