While I can understand the sentiment the current issue only happens
due to (among other things) the conflation of "entities available via
metadata" and "offering of all such IDPs for discovery" by the SP.
(Manifesting itself in the SP using the central federation DS, as has
been pointed out several times already. The SP will have to "filter"
IDPs (subscribers), so why not only provide those in a DS.)

Now ACOnet also doesn't intend to provide centralized fine-grained
mix-and-match metadata feeds or discovery services, but we do provide
several instances of a central ("fallback" as we call it) SAMLDS,
notably one including, and one not including, interfederation IDPs.

Obviously that doesn't "solve the problem" of non-subscribing
federation member IDPs showing up in services' DSs, but at least it
keeps it within .at (i.e., out of eduGAIN's wider community).
