If the point is not to let users even *try* restarting things if it
*might* not work, then I guess this might be reasonable.  

If the goal is to increase security by always requiring CAP_SYS_ADMIN
for "dangerous" operations, I fear it will be harmful.  We may have
people adding features that are not considering the security impact of
what they're doing just because the cases they care about all require
privilege.

What would the goal be?
