I doubt anyone is reading the column.  And if they are, they should stop.

pg_shadow and pg_user have been kept around because it is plausible that
a lot of tools want to have a list of users, and requiring all of them
to change to pg_authid at once was deemed too onerous at the time.  I
don't think this requires us to keep all the details the same forever.
