I doubt there are "some incorrectly applications", I think that is a rule rather than an exception.

Seems like we are starting Yet Another Bind Discussion!

Anyway, the peeking into bind variables is basically done when a hard parse is done. Hence, if multiple sessions execute the same shared SQL statement, only the first one will actually do the peek and hence, the optimization for all executions in all sessions will be as this first one.

In my opinion, cursor_sharing and bind variable peeking should be useless features. However, I realize there are some incorrectly written applications out there that can have marginal need for them.
