P: (Desktop) Please add Merge to HDR

You are correct that the new version of Lightroom CC does not currently include Merge functionality (HDR and Pano) at this time. However, the same merge operations that are in Lightroom Classic CC are also in Adobe Camera Raw (ACR).

First, you will need to save your originals out so that you can get them into ACR using "Save To..." in the File menu in Lightroom CC. At that point, the easiest way to get the images into ACR is to navigate to your exported photos in Bridge CC, select the images you want to merge, then choose "Open in Camera Raw" from the File menu. Once in ACR, select the images you want to merge, then right-click on one of the thumbnails and choose "Merge to HDR..." or "Merge to Panorama...".

Lightroom Classic is the updated version of Lightroom that still has all the old features, including merge.

The new Lightroom CC app is only at 1.0, but I'd be very surprised if it didn't gain merge in a future update. It just would have taken 10 years to ship if they added every Lightroom feature!
