Octavian, Thank you for clearly articulating your concern that Tk does not provide any support for screen readers.
While I believe that people can have legitimate differences of opinion as to whether this merits its removal/replacement from stdlib, there is no question that this is a serious and significant limitation of Tk. I will attempt to find out if there has been any work done in this area with Tk, and what it would take to address this important issue.
