"Developer unregistration notice alert" - real Facebook notification of spam?

Yesterday, I received this e-mail from “Facebook noreply@developers.facebook.com”:

"Unregistration notice

Hi, This is to inform you that your developer account does not have any roles on any apps (such as an admin). As such, to keep your developer account registration, we ask that you create an app or receive a role on an existing app within the next 30 days. If this developer account is not associated with an app by this date, this developer account will become unregistered. Please note that this will be the only reminder you receive in this time period and if no action is taken, this account will become unregistered in 30 days. Any removal of your developer account does not impact your personal Facebook account."

Below this is an icon “Go To App Dashboard”.

I don’t know of having any “developer account”, nor of what that means. I have a basic personal profile to my name on Facebook. Is this a “developer account?” Do I need to create an app in order to keep my personal Facebook account from being deleted, or is this some kind of spam?

I found this (hopefully it will be helpful/useful):
