Go do a fresh install of CentOS/RHEL (or just spin up a new docker container) and what do you see in root's bashrc?
alias rm='rm -i'
alias cp='cp -i'
alias mv='mv -i'
I've also encountered one job which adds this to their base ubuntu image, and my current employer uses Macs which have it added to bashrc by their mdm software on initial install.So what's your justification to dismiss the idea that this is a common practice?
