I should have made more clear in the JEP that the proposed APIs are
static methods on the List/Map/Set interfaces, not default methods. Thus
they won't be inherited by any subinterfaces or implementors.
Ah, static methods of interfaces behave differently to class methods.
The language corner case I'm missing is in 8.4.8 (of Java SE 8 JLS) for
classes
"A class does not inherit static methods from its superinterfaces."
and 9.2 for interfaces (if I've parsed this correctly)
"The interface inherits, from the interfaces it extends, all members
of those interfaces, except for fields, classes, and interfaces that it
hides; abstract or default methods that it overrides (9.4.1); and static
methods."
