I can't seem to find any documentation on the IPN message type "mp_notification". What is the point of this type?

Unfortunately we do not have this documented in our documentation. The IPN variables that you are asking about are related to billing agreements. Below is the information:
mp_cancel: Either the customer or PayPal has cancelled the customer’s billing agreement. Includes reason_code mp_2002 or mp_2006.
mp_notification: Either the customer or PayPal has altered the customer’s account. Can include reason_codes mp_2003, mp_2004, mp_2010, or mp_2011.
mp_signup: New customer sign-up for Preapproved Payments. Includes reason_codes mp_2001 and mp_2005.
mp_update: You have sent your customer through the Preapproved Payments billing agreement update flow. Includes reason_code mp_2008 or mp_2009.
These reason codes are related to changes in the buyer's account for billing agreements, they range from changing the billing agreement altogether, to removing all funding sources.
"mp_2001" // billing agreement created
"mp_2002" // user cancels existing billing
"mp_2003" // warning merchant of last funding source expiration
"mp_2004" // user got locked/restricted
"mp_2005" // user is signed up but pending verification
"mp_2006" // PayPal cancels existing agreement
"mp_2007" // user cancels during signup
"mp_2008" // billing agreement updated
"mp_2009" // billing agreement update cancelled
"mp_2011" // last funding source removed
"mp_2014" // bill agreement changed
I hope the information that I provided you was helpful
