Yeah, that should just work already. LLMNR uses single-label names,
hence resolving the unqualified hostname of local link-local peers
should "just work" if resolved and nss-resolve are used.

Note that link-local ipv6 addresses for the name resolution stuff
aren't fun to use in Linux right now, as the glibc NSS eats up the
scopeid, when a client wants to resolve a hostname and specifies an
address family. THis has the effect that resolving to link-local IPv6
addresses via "ssh" will just work (since ssh makes no restrictions on
the address family when resolving the hostname), but via "ping6" will
actually fail (since ping6 specifies AF_INET6 as address family...).
