Recent getty(8) changes clobbers w(1)

After the recent getty(8) changes w(1) will now show root logins on
the same ttys if you use su(1).  However, after logging out the root
user is not removed from the w(1) (or who(1) for that matter).

Example output from w(1) where tty p0 and p4 have been used to login
with root, and currently logged out while p2 is still logged in.

As far as I know this started after the getty(8) changes, but it could
be some other changes as while.  Am I the only one seeing this?

The machine is running world and kernel from 16th of June.
