In your example above both IDP A and IDP B are sending "givenName".
So simply ignoring "institutionPreferredName" and always using
"givenName" would be the obvious way to deal with this, no?
Or was just a bad example?

If the issue with mapping multiple wire formats to the same internal
attribute is duplicate values (coming from both
institutionPreferredName and givenName, in your example) the SP has a
feature to deduplicate values, IIRC.
