I think it's fairly obvious that in that situation, each of the registrars will make their own determination.

This isn't specifically about R&S, really, the same question could be asked about any other aspect of the metadata for the entity. The question should really be whether we move to a general situation where SPs have a single home registrar rather than making multiple registrations.

In this case, because I know you're talking about the UKf in the second paragraph, a simplified version of the question would be whether we should resolve this by working with the entity owner so that one or other of the federations takes responsibility for them, applies the R&S label (if appropriate) and exports to eduGAIN for the benefit of the other (and everyone else).
