Probably not.  One or two of them are actually useful.  For example,
if the shell has exportable aliases (which POSIX allows but does not
require), or there are alias commands in $ENV, running /usr/bin/alias
can tell you about them.  Of course, it can't change them usefully,
and `sh -c alias' would tell you just as well.  (That's actually the
likeliest of all the possible scenarios I was able to come up with.)
