Thank you for this.

Do you think such cross-version support would have been easier or harder 
if the major changes and deletions in 3.0 has been spread over several 
versions, such as 2.5 - 2.7. In other words, suppose the Python 3 idea 
never occurred to anyone and

2.5 dropped the old int division and finished the unification of int and 
long.

2.6 dropped classic classes and switched range, filter, and map to their 
iterator versions.

2.7 made unicode the text type

This is not purely a hypothetical question since the issue of spreading 
or bunching changes may arise again in the future.
