Name authority for Rumpole author

The author of Rumpole of the Bailey died this year.  As a result a death date was added to his name authority.

However, the new authority doesn’t include a cross-reference from the old authority.

I wonder is this an oversight?  or… a new trend?  I think there should be a 400 tag in the new authority containing:  Mortimer, John Clifford, 1923- 

and I have added this 400 tag to the authority record in our database.  I believe it is useful to users seeing as that was the way his name appeared in catalogues for many years.

The old authority:

Mortimer, John Clifford, 1923-
