Missing rules

[tdmalone]

This issue will collect rules that we’ve noticed are missing from this config. Generally these will be rules that need more investigation, testing, or possibly even custom rules written. If a missing rule is easy to add, skip this issue and just add it!

Feel free to change the priority label on this issue if important missing rules are added.

Please add checkboxes so rules can be ticked off when they’re included. This issue can be closed when we think we’ve covered everything!
