   **Is your feature request related to a problem or challenge? Please describe what you are trying to do.**
   I overcomplicated the design of the FilterNullJoinKey rule. There is no need to check for a combination of null and non-null join keys. Instead, we just need to add filters for any join key that is nullable.
   
   **Describe the solution you'd like**
   Just add filters for nullable keys on either side.
   
   **Describe alternatives you've considered**
   None
   
   **Additional context**
   None
