Strange thing to say.
There may be new config options. The defaults may be altered with good reason.
This needs a new file

OTOH the user may have his own old altered defaults.
So integrating the two is not exactly an easy problem.

And what apt does in this case is to drop you into some half-assed

want to keep old, choose new, drop into a shell, or some other half-baked
