I created an enhancement request JDK-8298602 to start a discussion about the state-aware caret implementation so we can come to a more flexible solution in the future. With that in mind can we come to some conclusion on this exact accessibility issue? I still thing it is beneficial to have a way to distinguish between focused/non-focused and editable/non-editable text components and the caret seems to be potentially less destructive change. I do not see any major UI element that has the text component embedded that is affected in the negative way by this change.
