To be precise, if "/bin" were searchable but not readable, no one *using the
C shell* could use PATH to find anything in it, presumably because "rehash"
scans the directories in the PATH; neither the Bourne shell nor the Korn
shell, whose similar hashing mechanisms add items to their tables only when
a command is actually run, have any problem.
