I did push for all my digital images to be DNG, and they are, up to around 2018, and two out of four cameras use it natively - Pentax, Leica - while the other two use their own formats - Canon, Fuji.
The reason I’m less fussy now is because the combination of edits, metadata and image data in a single file didn’t necessarily help me when I switched from Lightroom to Capture One. I would love to be able to update the files to use newer RAW processors and better IQ, but I lose the Lightroom edit information in C1. That makes sense as they do things differently. But I hoped that with DNG there was a universal format for handling edits.
My JPEGs remain the definitive version of the images but I would love to be able to recover all those original edits again in C1, or any other editing program.
