pbkdf2 with SHA-1 algorithm still a secure default?

[WardPearce]

Greetings, My brain panics whenever seeing SHA-1, after doing some research appears SHA-1 is still considered secure for key derivation (this site seeming the most reputable).

Just wanting to see if anyone had any information if SHA-1 is still future proof for pbkdf2 key derivation? What would be the benefit of using SHA-256?

Also appears the documentation for changing the algorithm isn't apparent.
