/**
 * Changing the address a password reset would be sent to is a credential
 * change, and it was the one credential change on the profile screen that
 * asked for nothing.
 *
 * The chain the report walks: a stolen session PATCHes a new address, the
 * attacker asks for a reset there, and the temporary session becomes
 * permanent ownership. Deleting the account, one method further down the
 * same controller, has always required the current password — this is the
 * same rule, on the door that leads to the same place.
