Subject: Closing a privilege escalation

With some arguments, emacs started inside sudo will run the user's own
.emacs file rather than root's. This creates a known vulnerability
for privilege escalation.
I propose a feature to fix the vulnerability:
For sudo-authorized users, require .emacs (and other Emacs startup
files and directories) to be owned by root.
This won't be a big hassle for them, since
these users can sudo to edit their root-owned files.
Do people see any problem with this?
