How?

Command lines that previously worked will continue to work.
Command lines that should have worked, but didn't, will now work.
Command lines that shouldn't have worked will still not work.

The only scripts that may fail are those doing negative testing to check for
a form that *should* have been allowed--quite clearly, any such negative testing
was incorrect.
