Do you need to set SPF records when sending mail with Google Apps account sender?

According to the Google Apps docs, SPF should be set manually.

And indeed, there is no such record in the DNS setiings of the domain.

However, when sending mail via App Engine, Google seems to add SPF
automatically. At least that's how I interpret the headers on received
mail.

Received-SPF: pass (google.com: domain
of ...apphosting.bounces.google.com designates 209.85.160.208 as
permitted sender) client-ip=209.85.160.208;
Authentication-Results: mx.google.com; spf=pass (google.com: domain
of ...apphosting.bounces.google.com designates 209.85.160.208 as
permitted sender)

I've set it in the DNS settings and had it no effect, other than what
was already in the headers.

Well, I've figured it out. App Engine sends the mail via
*.apphosting.bounces.google.com, so SPF checks against that domain
(and not the app domain). So to answer my question: no, because SPF is
already set by Google. However, when sending from Google Apps, SPF
needs to be set in the DNS settings.
