Well, I don’t know if there is a rationale for this choice.  Somehow, my
understanding is: 1. python-django is byte-compiled using one specific
Python interpreter and 2. what is the guarantee that the whole code
byte-compiled with different Python interpreter will run?

Hence, that version of the specific Python interpreter is encoded.

Now, if the purpose of ’django-admin startproject foobar’ is to only
create generic configuration that does not depends on any Django or
Python version, then maybe it could be considered as wrong. :-)

Else I don’t know.  I remember having a similar discussion about a
similar Python tool but I am not able to find it back.

Cheers,
simon
