And you instantly thrash performane on any server that doesn't, which
is why I sent out the errata that no one objected out.  I'm happy to
open this again on the WG list, but the notification scheme is such a
big hammer that it absolutely isn't worth implementing.  Given how
GETDEVICELIST is specified in 4.1 the original RFC language also is
inconsistent with itself, so that's not an argument for the old
behavior.
