Probably we need a document in the IETF that clarifies that IPv6
specifications involving ascribing addresses with link-specific
properties, including but not limited to:

    [1] subnet-router anycast
    [2] general subnet anycast addresses a la rfc2526
    [3] the whole U and L bit mess

are recommendations specifically to the operators of the logical
administrative domain in which that link resides (or to the group of
operators if responsibility for a given link is shared by more than
one administrative domain) ONLY, and that link-specific properties
CANNOT reasonably be inferred by entities outside the responsible
operational domain(s).
