Most of the non-'bin' executables are either suid or sgid,
and need to belong to the owner/group that they operate under.

Doing a "chflags schg ..." will prevent them from being
easily modified/hacked and likewise prevent the necessary
permissions from being accidentally changed. 

As far as UID 'bin' not being secure, as I understand it, 
having the files owned by 'bin' is the same as having them
owned by just about any other non-0 uid. It's the suid/sgid
bits that cause potentail holes.
