Bash guys hate to see HISTFILE set to /dev/null, and they say it is
stupid to do so.
In their mind, setting HISTFILE to /dev/null or any other character
device leads to vulnerabilities for now.
However, they are willing to deal with the HISTFILE issue because bash
shouldn't delete /dev/null in any case.
If bash guys consider it as a vulnerability, I think it is wise for
emacs guys to avoid it on their side.
