No objections to changing the default to false in 10.0.x but I think removal/deprecation is a step too far. Not everyone uses the full u...@bigco.com format as the "primary key" in their internal user database. I see lots of variation depending on which system is viewed as the source of truth to which other systems are synchronised. We have X509UsernameRetriever for certificate authentication. That came out of bug 52500 where the aim was to support a wide variety of formats. The root of that requirement was essentially the same - integration with a variety of systems where the user name could be in in a range of formats. The mapping of that format to an X509 cert just added another layer of complexity. If there was user demand for it (I haven't seen any) I'd support a similar interface for SPNEGO. With such an interface in place, deprecation and removal of stripRealmForGss would make sense.
