I generally agree.
My reasons for keeping separate /,  /var, and /usr
has been / is  to provide some degree of protection
from corruption to the file system. If all of these were
under /, then a corruption in / would make the other
two also inaccessible. So They indeed ought to be kept
separate for that reason, to minimize loss.
