Ordinarily I'd defer to the old EU::I behavior too, but it doesn't  
make much sense to me in this case.  If you preserve the timestamp  
blib->install, you get an essentially meaningless timestamp.  If you  
also preserve lib->blib then you get a potentially dangerous  
timestamp, where you could replace files with things that look older.
