So, like I said it's a convention, not a requirement.
BTW, the %<interface> format is a standard and can also be used with ping6 instead of -I.
Then you'd have to worry about different ways of using those apps when there's one or more than one interface. Right now, you have to specify the interface no matter how many there are. And yes I know about % with ping6, but -I is listed in the man page.
