I found some Unicode bugs in porting—and I get continued free security updates. Seems fair to me, and certainly not “no benefit”. I can keep on 2.7 as long as I like; nobody’s forcing me to port. Compare the situation with Java!
I like Python. But it loses in the upgrade comparison to Java. Existing Java code almost always just keeps working with new compilers and JVMs. And new JVMs tend to increase performance of your code for relatively little upgrade effort.
Isn’t that comparable to java? Oracle gives you paid security updates on version 8. You can keep using the previous version without security updates or migrate to OpenJDK 8, which have their own security group. More options, seems better to me.
