Looks like Nick Ing-Simmons is quite busy and he do not appear on perlTk mailing list unfortunately. He appears on perl5-porters quite often.
(I hope I do not do anything bad by discussing absent people offline)

Anyway. he released Tk804.024 that is quite alpha, and then Slaven Rezic prepared a special update patch to that release, also available on CPAN, and I remember discussion between Slaven and Nick about this, and they decided current situation as quite acceptable.

Courage, the Cowardly Dog
