Apologies for the fragmented response (bad night on the Caledonian Sleeper) 
but the other thing we may want to look at again in the UKf and elsewhere are 
the consequences of more widely adopting the compromise we ended up with for 
the GÉANT Code of Conduct:

This isn't a complete solution by any means (you still need something like 
the meta-attributes idea to handle the hard cases around identifier choice) 
but I'm inclined to think the downsides are becoming less significant as we 
get more SAML 2.0 adoption.
