This is still VERY much needed. The request really has nothing to for me about editing. It has everything to do with sharing. I want people to be able to download the files in the same resolution/dpi that I created them. Dropping everything to 72 dpi is ABSURD! I can live with downloads being converted to JPEG. But PLEASE let my work be used they way I intended. STOP altering it. Changing the dpi is dramatically changing the quality of the photograph.
I really like the Lightroom suite of apps. I still prefer Lightroom Classic to Lightroom CC but I think you will get there in time. But it is insane to have this cloud based solution with sharable content and then ALTER the content to share it. I end up having to export the photos and then upload and share them on Google Photos, Amazon Prime Photos or Microsoft One Drive to provide anyone with reasonable quality photos for download.
At least give us a download quality preference setting. I had updated my Photography plan to the 1 TB option so that I could do exactly this. It is a complete WASTE of money.
