This will install python3.5 on this system regardless if there is a working python2.x installation, which is exactly what is wrong. I am a software developer who runs legacy systems on python2.7. Forcing ports that are able to run with python2.7 to install python3.5 will most probably break my systems. USES should always represent the minimum requirement not something so feel is something it should use. Please do not break systems without a really good reason. This we can discus in 4 years when support for python2 will end, but not until than. Not everyone has the freedom to run only shine new software on shine new systems.
