I was a big fan of WxPython myself.  I waited for Phoenix for a while, then decided to learn PyQt5.  Having been exposed to both GUI's ways of doing things, I'm not sure which I prefer.  I never liked Tkinter.

It's true, I only have about 25,000 lines of code.  My largest program suite is only about 10% of that.  And indeed, it's now all in Py3. The 2to3 utility took care of most of my porting needs.  Yes, I aspire to the DRY principle.  I've written a few packages which extend Numpy's behavior in specific ways which I've re-used many times.

I acknowledge that there's a vocal group of Py2 users who have decided that it's too much trouble to switch.  The PSF has decided that its energies are better expended on growing Py3 than on maintaining Py2 for that diminishing user base.

But no one owns Python.  There is no law that states that Py2 adherents cannot maintain the language themselves, if they want it.  Sheesh.  Just do it.  Make it yours.  

Or make something better if you want.  You state:

If you have all the skills that you claim, you're a far better programmer than I.  So -- exactly why are you complaining to people who are developing and/or using Py3?  Go off and impress everyone.  Become your own BDFL.
