Don't say "dangerous" for _root_ user. Is there any purpose left for being 
root anymore? According to your logic, all root operations should be 
disabled by some unknown undocumented sysctls because it is too dangerous 
to be the root. Better kill yourself than to be the root.

Does anybody asks for protection here? It was not me. It was not majority 
of Unix sysadmins. Such kind of protection should be turned off by default 
in case it even exists as the toy for some paranoid people.

boot0cfg not works (I assume the reason is the same).

I can't write FreeBSD bootloader because reinstalled Windows overwrite it 
with standard MBR and sysinstall don't allow to write bootloader anymore. 
The only thing I not try yet in that situation was 'dd' - I was too lasy 
to find needed byte.
