There is always SELinux which can limit root. It was fairly easy to setup last time I tested it, and there has been attempts in the past to put it in as default.

A lot of distros also alias "rm" to "rm -i", something that many users explicitly disable. Its a complex problem of security vs usability where most discussions has been rehashed several times.

Personally i find rm too accepting, and rm -i too restrictive.

Using rm on its own will happily perform the command without further verification.

On the other hand, rm -i will request a yes/no on every last file involved.

Personally i have taken to using mc for any "complex" file system manipulations.
