A possible (remote) reason for not doing this is in environments using ACLs that somehow want different access permissions on some functions vs. others AND where the platform does not have the ability to separately secure links vs. objects. I don't know of such an environment, but you never know. I know it's a stretch, but I can see security-types being worried about this. I do know of environments where /usr/local/lib is secured differently from /usr/local/bin to prevent inappropriate .so loads on a selective basis, so there's that. Again, this is a stretch. As long as we continue to have a method of forcing the expensive way for the paranoidly inclined ;)    -- not meaning offence to those, of course.

Cheers,
Randall
