I've seen implementations where no route was injected (to customer astonishment of course becase it's useless without this), so this is functionality that needs at least some kind of specification.

I'll keep my eye out for it.

I guess my impression from RFC8415 was that it was up to the network administrator and their equipment vendor to resolve this.  Certainly, I wouldn't have expected automatic route injection, though having such a feature available is of course really nice.  Some sort of standard behavior for it is preferable if it's going to be implemented.

My punt in the absence of support for it on my platform (I'm arguing to get it implemented) was to inject the route via BGP from the DHCP lease database.  That's very flexible, but it's also a heck of a lot more work of course.
