Why am I seeing this message about 'esm-apps' on just one system?

Hi,

For my Ventoy's Xubuntu 20.04.5 LTS different packages were mentioned
and I didn't enable anything related by myself.

FWIW on my Ventoy's Xubuntu 20.04.5 LTS those are the defaults I got
after attaching "pro":

IOW it does look different to
https://lists.ubuntu.com/archives/ubuntu-users/2023-March/309654.html .

Note, 20.04 LTS is still within standard support, so I suspect there
should be no need to attach "pro" to get all security updates.
