It sounds like we could add these check types to my script:
- desktop-file-sanity (always waive?)
- IP v6 (always waive using existing waiver details, eg., https://errata.devel.redhat.com/rpmdiff/show/182126?result_id=5028358
- patches (waive if %autopatch)
And if the only other complaints are "patch not applied" (I'm not sure if this check may throw different kinds of error)
So, the next time we have an errata with the above types of issues, I can update this script  to add those use cases.
