What problem are you facing?

Given that:

• This function's configuration is complex.
• The render command does not currently work for status conditions (the example/ directory of this function is not useful).

This results in a more difficult user experience as the user will need to experiment with the function on a live server.

How could this Function help solve your problem?

Once status conditions are added to the render command (crossplane/crossplane#6121), we should add some use-cases to the example/ directory. This will improve the user experience of this function.
