Of course that's one of the ways, I suppose :)

chflags is useful but root limitation feature is not useful
for common users I suppose. With our expansion, common users
can check files or directories on self-responsibility.

And unusual commands like chflags I just suppose are no much
point in this case. What is important is that adding mistake
protecting functions into common commands like rm(1) itself.

Of course I respect your opinions and all comments are
welcome :)  I have no intention to add our expansion to src
tree. It just is a little patch for folks who have a interest
of it. Thanks
