I mean that the interface has a routable address, and the v4LL mechanisms
are not invoked to assign a 169.254/16 address to the interface.

I don't understand the difference between the two alternatives you've
presented.  I also don't understand, from below, "and the working routable
address is mapped over as the v4LL address".
