Sony ILCE-1 camera support - JPEG compression?

Unable to open file in darktable ( maybe this needs to be in rawspeed )

[rawspeed] (ilce-1_DSC0735.ARW) virtual rawspeed::RawImage rawspeed::ArwDecoder::decodeRawInternal(), line 149: Unsupported compression

I think the ARW is uploaded to raw.pixls.us - though I can't find it after uploading.

Btw, I found it a bit strange that this new compression mode has

Exif.SubImage1.ImageWidth                     8704
Exif.SubImage1.ImageLength                    6144

as opposed to 8672x5784 of the uncompressed or lossy compressed...

Even though 512x512 tiles are used, the TIFF writing/reading libraries should handle desired size and pad/crop tiles along the right and bottom borders automatically, right? I don't think there is a requirement to set the size to be an integer number of tiles, so not sure what Sony is doing here...

As a result, the generated info on RPU is a bit whacky as well (should still be 3:2, 50.16 MP and say "compressed"):
