Content validation still blocks some items even when permissive

I noticed if I had a yum hosted repository with a permissive deploy policy if I curled in a nuget package, then I still got blocked by invalid content type detection as shown below.
My understanding from the setting and documentation is that permissive means you can add anything. I believe this is how it works for other formats with validation.

e.g.

curl --user admin:admin123 "http://localhost:8081/repository/yum-hosted/Packages/SONATYPE.TEST.1.0.nupkg" --upload-file SONATYPE.TEST.1.0.nupkg --request PUT -v
...
< HTTP/1.1 400 Detected content type [application/x-tika-ooxml], but expected [application/zip, application/octet-stream]: Packages/SONATYPE.TEST.1.0.nupkg
