Preservation of intent data across login redirects > MUST?

The section on authentication (5.6) reads:

"Intent data should be persisted by the User Agent across login redirects."

Are there reasonable cases where login is successfully negotiated AND
where the UA would not preserve the intent data? Should this be a
"MUST be persisted"?
