Funny, I found the exact opposite, and despite $dayjob being LCD(2, 3) and the default Python on my system being 2, I've been writing all my small scripts in 3.6.
The real crime of Python 3, is not the changes, but the compatibility break. Hundreds of thousands of engineer-hours wasted on porting, worrying about compatibility, and supporting unsupported libraries or two environments at once. In the meantime, the language does not meaningfully advance, and thousands of projects are slowed down. It's such a huge effort for a gain that is not worth it.
