Frank,

The RGBA interface looks like it still works ok on such files. And reading the raw Y, Cb, and Cr data looks right for this particular file. However, I'm seeing a couple of files produce some "drop-out lines", but all of these files look like they also produce that old warning

  JPEGDecodeRaw: application buffer not large enough for all data

I'm going to spend a bit more time trying to characterize this.

It sounds like you ought to file a ticket on this. It may be that the changed behavior is intentional. If the tag isn't really there but is deduced for processing it may be that it is not considered desirable to expose it as if it were really a tag.

On the other hand, this might well just be an unintentional side effect of other changes. Certainly this area is super fragile.

Does this break normal processing of the image? For instance does tiff2rgba fail?
