I'll happily debate the merits of breaking compatibility in general, but it's boring and completely academic for Python 3 which is getting on for a decade old and has very wide community support. Same thing every Python thread. It doesn't matter if you liked the way 3.0 was handled (and there certainly was complaint at the time too), it's what Python is now, and that's that.
