Yes, we're aware of the imminent deprecation of Python 2.7, and even now (while its still officially supported) we're aware of numerous obsolete features in its source code: the very latest 2.7.16 release gives many deprecation warnings when you build it on a C++17 compiler.
Even so, we're a relatively small player within our industry, and among our customer base even Python 2.7 is cutting-edge: there are still commercial tools available from other vendors based on Python 2.6! Whether we like it or not we'll be tied to Python 2.7 for quite a long time, and will have to find a way of supporting it.
