Bastian, I did see your email about 2.13.2-alpha, but it is alpha and thus belongs in experimental. I don't know if it is (the URL you gave for the .dsc is returning 404's) so I've removed the NMU.
As for the removal for Python2 - they have made a lot of noise for something they haven't secured broad agreement on. I personally doubt it will happen. There are a lot of python2 programs out there running on debian boxes, most which is just scripts written by sysadmins. Removing Python2 would force a lot of users to not upgrade bullseye, or move away from Debian to something that still does support Python2. Note that just about all major distro's do - Debian's stance is peculiar in this regard. Removing programs that depend on Python2 in the archive may be possible, but it still sounds too hard to me. So my attitude for now is wait and see. If a stable version of spyne that supports python3 is released in the mean time it will end up in Debian stable, and the problem will disappear. I'll leave this bug open for now to remind me to look for a stable version of python3 spyne.
