Based on https://godbolt.org/z/TqoWTxT75 the change would disallow using a `string_view` instead of making its usage more efficient. I wonder whether this change in behaviour is intended, especially since the title suggests differently and the LWG-issue doesn't change Annex C. @jwakely is the change in behaviour intended?

Yes, that was what LWG suggested and LEWG approved.
