As this enables i.e. the hosting system of a vm or container, to track activity inside the container, trust is lost i.e. from customer to hoster. To be fair, you need to be root on the host to do this, but as it "wasn't possible before", and it is "now" ( out in a greater public ), it tends to create trust issues, just for being there*.

*) You may not have a clue, what security auditors tell you about "a vulnerability & it's just there, but inexploitable". I had a case 2 weeks ago, about a missing patch for the ssh-agent CVE vulnerability in fedora's openssh. Trust me, it will create trouble the more the topic is discussed in the pubic.

Auditors are constantly proposing disabling features and making things
inconvenient, undebuggable, inefficient and substantially annoying to operate.

They should instead learn some basic concepts of security.
For example: if you are running a process, even in a VM or container, you have
to trust the administrator of the host system. And that's it.
