Yes, all link-local addresses have this issue, however the problem with IPv4 link-local addresses is typically mitigated by only having a single network interface bound to the link-local subnet (e.g. cross-over cable direct to printer) while IPv6 allows link-local on any subnet so clients can't make any assumptions if they have more than one network interface (pretty much the norm these days...)
