Why is the iteration needed if I choose sufficiently strong passphrase? Think 40 characters


If your password is very long and randomly generated and not used anywhere else then probably not. But it doesn’t hurt.

The iterations count regulates how fast an attacker can check a guess of the clear text.


It's not really needed if your password has a lot of entropy. 40 random characters is like 256 bits or something so that's crazy overkill and would be safe regardless of how many iterations.
