This is actually due to a change in sudo. See this reply:
https://mail-index.netbsd.org/current-users/2023/10/04/msg044487.html
An easy reproducer is:
$ sudo sh -c 'echo hello | wall'
You would see that double message only on the _current_ terminal because
sudo creates an additional one. All other terminals will see only one.
