As a developer I’m annoyed with having to install third party packages to get access to Python 3. The software Apple ships is also code-signed, which is important to some organizations which relies on binary whitelisting (e.g. github.com/google/santa). Software from Homebrew or Anaconda are typically not code-signed.
I was hoping that perhaps bringing the old Python 2 interpreter up here could lead to more radars for the inclusions of a recent Python 3.x release in the base system.
