Standard file permissions for /usr/local

I suggest that for various management purposes, it is not pointless,
and if not u+w, it's otherwise annoying.

drwxr-xr-x  10 root  wheel      512 Jul  7 18:43 .
-r--r--r--  1 root  wheel  0 Jul  7 18:43 1
-r--r--r--  1 root  wheel  0 Jul  7 18:43 2
/bin/cp 1 2
cp: 2: Permission denied

I 'fixed' my tree,  so not that I care, just curious as to what standard
or non nonsecurity rationale I may be missing.
