The scripts from python3-docutils have a shebang line that specifies 
python3.  If you invoke them by name (as opposed to 'python <script 
name>'), they will be run by python3.  It would be possible to package 
both versions by including the python version as part of the name, as is 
done with easy_install-2.7 and easy_install-3.6, for a good reason.  But 
I'm not aware of any such good reason to go to that trouble for the 
docutils scripts.

See 
https://fedoraproject.org/wiki/Packaging:Python#Avoiding_collisions_between_the_python_2_and_python_3_stacks 
for a detailed discussion of how this issue is handled by Fedora.  In 
particular:

"If the executables provide the same functionality independent of 
whether they are run on top of Python 2 or Python 3, then only the 
Python 3 version of the executable should be packaged.  Transitioning 
from python2 to python3 is left to individual package maintainers...."
