Not really. As I mentioned, Chirp is targeted at Python 2.7. All Python
2.6.x syntax is valid in 2.7, but 2.7 adds some new capabilities. It's not
strange that someone would want to take advantage of those new capabilities
when they're available as part of the target version.

This is not really different from someone working in C++. If the target
version was C++11, any code written for C++98 or C++03 would still be fine,
but there are new features - and new syntax - that can be taken advantage
of in C++11 to make life simpler / more robust. Code written using those
new features may not compile with an older compiler.

Also, I'll note in passing that Python 2.7 was released 10 years ago, and
security updates for Python 2.6.6 were stopped 7 years ago, in 2013.
