3) package the LTS version for python 2 and the new version for python 3.
+1 to this one. something similar will happen with django that is dropping
python2 support

In the third case, wihich consider the best approach, do I need to
create
a new package and go through the review process?
The main package python-astropy can keep providing the python3-astropy
subpackage as per the current packagin guidelines (some time in the futere
python-astropy will point to the python3 package and not the python2
version with the help of the %pythonprovides macro)
A new package python2-astropy should be added to the distribution
