just curious why this is added? is this expected?

Seems like this spec has an anonymous model for MFD which isn't properly supported yet. FileContents should be used in uploadFile but is currently Uint8Array. Will fix.

Will address anonymous models including this case in a follow up issue

should we add a case for
model RequestBody {
files: HttpPart<File[]>;
}

I don't think that case really makes sense. That body model would represent a single part consisting of a JSON array of File objects.
We do already have a case for a JSON array here.

I wonder if we could use usage to filter the HttpPart models out?

We can't because tcgc doesn't set UsageFlags.MultipartFormData for Http.File. It only does that for the actual multipart body model.

I wonder why we need this filter? do you see any cases where there's duplication?

Yes, the multipart payload cadl ranch spec causes this duplication for some reason. If you revert this change and regenerate you should see the issue.

I feel like it's strange if an operation group would appear multiple times. how could I repro?

Same issue as above -- without this the multipart spec generates the group 3 times. I think it might have to do with the way that the operations are nested?
