Is sys.executable not supposed to follow symlinks?

I don't know about guaranteed, but it's certainly the behaviour I
would expect. Recognizing the invocation executable is important to a
lot of commands that behave differently based on that, for instance
with the detection of a virtual environment. The fact that the
executable might be a symlink is irrelevant.

If you want to follow symlinks, you can always readlink on it.
