Unless I am misunderstanding you, that's what the <alt_string> is for.
That means, if the optional argument is not found, the [...] placeholder
would be replaced by the alternative string as described above.

I'm not sure if this is flexible enough.  The scheme does not cater for
the situation where one wants to use a completely different string if
the optional argument is not found.  For example for "\item[foo]" you
might wanna display "foo:" but for "\item" just "*".
