Oh, I thought the next genshi release was just around the corner. I
didn't realize that development was stalled. Ok, then. If other distros
are using these patches without problems, let's also have python3 genshi
and relatorio packages.

But, let's build trytond with python2. GNU Health still needs trytond
3.8, and trytond 3.8 only supports python2.
