right, but it's an all-or-nothing or a try-and-filter-based-on-some-fuzzy-
matching approach with the galago spec. it simply isn't built for treating
different notifications differently or allowing for configuration of them.
that's ok, i don't think the galago spec should be bent in this way. it should
do precisely what it's doing: notify the environment that "this visual
notification needs to be made".
now, the major drawback i see in galago is it allows for one visualization
only since it targets a "well known" dbus address, unless you multiplex that
in the server and re-emit to N different visualizations.
what would make sense to me is to allow a mechanism by which other
visualizations can register themselves as listeners to visual notifications,
each of which would get sent the data.
in the common case, there would be one listener and everything would be just
as-is. it is not unusual to expect to show the same body of data, or subsets
of it, in different places/ways.
that, however, can be done outside the spec with an implementation-specific
dbus service that takes registrants which speak the same galago dialect.
but then we're getting into something more like knotify. and really, that's
how galago probably ought to have been designed from the start: an interface 0
to N objects on the bus can implement to show visual notifications to the
user, with those objects registering themselves with a well known interface.
perhaps something to take into consideration in a new, full notifications

there is no need for KDE to switch to anything. we're using the galago spec
(or a modification of it, currently, hopefully not after your patches go in)
to relay visual notifications from knotify.
let's not more this difficult than it needs to be by confusing what knotify
does with what galago does and how we've implemented each in kde 4. i really
don't want to go through the whole "this is not a replacement of knotify with
something less capable" thing again with my KDE teammates.
galago and knotify have essentially zero overlap in functionality. in fact,
knotify provides a notification _system_ that feeds the service defined in the
galago spec with data to show.
