Yeah, I guess that would make some sense, given that python2 is now EOL.

Otoh, making it gratuitously not work with python2 seems a bit harsh.

On the gripping hand, reading PEP 0394, I see it doesn't actually 
require that 'python' exist at all, so I guess changing the shebang as 
you suggest is the right thing to do.
